Stem cells derived from bone marrow, or hematopoietic stem cells, are a topic of significant debate in the medical community. While they have exhibited significant potential for benefiting people with both cancerous and noncancerous diseases including immune deficiencies, not all methods for administering bone marrow are created equal. While intra-articular injections of bone marrow are more common and considered safer, intravenous methods pose serious risks, which are explored here.
Intra-articular injections involve injecting bone marrow directly into the compromised joint, whereas intravenous methods entail infusing bone marrow stem cells into the body through the veins. Intra-articular injections have shown promise in treating conditions such as osteoarthritis (OA) in joints such as the knee and has proven to achieve pain relief for moderate-to-severe cases of osteoarthritis.
Intra-articular treatments are localized, so the injected bone marrow is already in its target location upon being administered. According to research, this form of therapy is generally considered to be safe. In intravenous bone marrow transplants, however, there are serious risks associated with treatment. Bacterial infections are common, while viral and fungal infections can also occur and cause life-threatening conditions, such as organ failure.
Risk factors for developing any complication associated with intravenous bone marrow transplantations vary based on a number of factors, including the patient’s age, genetics, and type of disease being treated. With that said, due to its limited risks, intra-articular bone marrow methods appear to be the safest form of treatment currently available. Although each patient will need to discuss risk factors alongside potential benefits with his or her physician, oftentimes the risks appear to outweigh the potential benefits.
There are alternative therapies with fewer potential side effects which may be explored such as Adipose and Umbilical Cord-derived stem cells. These regenerative medicine treatments not only can treat osteoarthritis and sports-related injury conditions, but have also shown positive results in treating neurological conditions such as Multiple Sclerosis, Parkinson’s disease, Post-Stroke, and Traumatic Brain Injuries (TBI).

Using growth factors to help stem cells differentiate into chondrocytes, or cartilage cells has been shown to be an effective way to maintain cartilage tissue. However, there are several different types of growth factors, and little has previously been known about which growth factors may be most beneficial for help stem cells differentiate in a way that supports cartilage.
New research published in Stem Cell Reviews has addressed this issue by looking specifically at how four specific growth factors affect differentiation of mesenchymal stem cells – and particularly – how they affect chondrogenic differentiation. The four growth factors explored in this study were: transforming growth factor beta 1 (TGF-β1), bone morphogenetic protein 2 (BMP2), parathyroid hormone-related protein (PTHrP), and fibroblast growth factor 2 (FGF2).
The scientists used methods of analyzing the levels of growth factors as well as the extent of collagen content on days 16, 23, and 30 after implementing growth factor programs. The results showed that TGF-β1 and BMP-2, when used in combination, increased short-term collagen content and other indicators of well-maintained cartilage. When PTHrP or FGF2 was applied, the overall impact of TGF-β1 and BMP-2 on cartilage tissue was initially decreased. Nonetheless, successive applications of both PTHrP and FGF2 helped to maintain the effects of TGF-β1 and BMP-2.
These results help to clarify the ways in which growth factors can be used to improve the ability of bone marrow derived mesenchymal stem cells to differentiate into cells that are viable for supporting cartilage. The specific outcomes provide critical information that can help with protocols for chondrogenic differentiation of stem cells. Future research will likely build on these findings to help scientists and clinicians better understand the best formulas for how to use growth factors to achieve desired results with stem cells.

Adipose treatment is a procedure in which stem cells are derived from a section of the abdomen then used for therapeutic purposes. Adipose-derived stem cells (ADSCs) are less invasive to extract compared to cells derived from other sources, such as bone marrow. In therapeutic applications, adding platelet-rich plasma (PRP) to ADSCs has been shown to have benefits.
What is PRP?
PRP therapy is the process by which a small sample of blood is removed from the patient. The platelets are then separated from other components of the blood via a centrifuge. The isolated platelets are shown to have high levels of diverse growth factors.
Why Are Growth Factors Important?
ADSCs are shown to have reduced proliferative potential. While they do secrete a wide range of growth factors, PRP therapy is coupled with stem cell therapy to maximize their regenerative medicine potential benefits by helping to increase their proliferation and differentiation. PRP essentially empowers the ADSCs, stimulating cell proliferation and cell differentiation when used for regenerative applications.
Which Applications Can the Therapy Be Used for?
Researchers have stated that the therapeutic potential of ADSCs is “enormous,” but by kickstarting the stem cells with PRP, it’s possible that the therapy will unlock even further medicinal possibilities. Anti-inflammatory and anti-apoptotic effects have been demonstrated by ADSCs, and there are many clinical trials which have either been completed or are ongoing to explore the treatment’s effects. Skeletal repair, soft tissue generation, and immune disorders such as Crohn’s disease and multiple sclerosis are just some of the therapeutic targets for this treatment. In specific, using ADSCs with PRP has been shown to aid periodontal tissue engineering, tendon repair, wound healing, and even bone regrowth.
Because the ADSCs are fairly easy to source and blood samples required for PRP are also simple to acquire, combining PRP to adipose stem cell therapy shows promise for delivering a powerful treatment that can address a broad variety of conditions, all with a minimally invasive approach.

Under normal circumstances, pain receptors react to painful stimuli such as burns or lacerations. Pain receptors from the body then send that information along nerves to the brain via electrical signals. Once that electrical information reaches the brain (which happens almost immediately), it is perceived as pain. This type of pain is a nociceptive pain.
Neuropathic pain, however, is different. Neuropathic pain is caused by a condition of the nerves themselves. Patients with neuropathic pain experience chronic pain without any specific injury. Neuropathic pain may be felt as a burning sensation, tingling, or a “pins and needles” sensation, or these combined. Neuropathic pain most often occurs in people with diabetes, certain vitamin deficiencies, and shingles. It may also occur after people receive certain cancer treatments following a stroke.
While it is rather simple to treat pain caused by a burn or laceration (nociceptive pain), it is very difficult to effectively treat neuropathic pain. Standard treatments for neuropathic pain include anti-epilepsy medications such as phenytoin, gabapentin, or carbamazepine and antidepressants such as venlafaxine, duloxetine, or amitriptyline. Usually, these treatments are only modestly effective. Eventually, many patients need powerful opioid medications like morphine and oxycodone to control their pain.
Researchers at the Cleveland Clinic published research that strongly suggests that stem cells may be able to improve those battling neuropathic pain. Dr. Jianguo Cheng and his research group have shown that mesenchymal stem cell transplantation into the spinal fluid can reduce pain and pain sensitivity in an animal model of neuropathic pain. In one series of experiments, they showed that mesenchymal stem cells could relieve pain in rats who had experimental nerve damage. Researchers confirmed the benefit of stem cells for neuropathic pain in several different sets of experiments. The results have been so encouraging that Dr. Cheng and the Cleveland Clinic have applied to patent the technology.
Dr. Cheng’s group also showed intravenously administered mesenchymal stem cells are just as effective as cells administered into the spinal fluid (intrathecally). This is good news for patients since it is less invasive to put stem cells into a vein than it is to infuse them into the cerebrospinal fluid. Amazingly, the research group showed that stem cells injected through either route (vein or spinal fluid) ended up finding their way to damaged nerves where they could provide maximum benefit.
While this work in animals must be performed in humans to confirm the results, this preclinical research establishes a strong foundation for those clinical studies. These results provide hope to those who struggle with daily neuropathic pain.

A technique called hyperbaric oxygen therapy (HBOT) has been shown to help patients with traumatic brain injury (TBI) who are suffering from a chronic neurological injury. HBOT appears to confer its benefits to these patients by increasing the neuroplasticity in the brain – or, in other words, by making it easier for the brain to re-wire itself. When the brain has a higher degree of neuroplasticity, it is easier to recover from neurological injuries because the brain can find ways to re-wire and restore functions that were lost due to damage to brain tissue.
A new study, published in Frontiers in Human Neuroscience, investigated the effects of HBOT on prolonged post-concussion syndrome (PPCS) that occurs as a result of TBI. The researchers used imaging strategies to monitor the brains of 15 patients with PPCS and evaluated the patients with tests of cognition. The researchers gave each patient 60 treatments with HBOT. The treatments were initiated anywhere from 6 months to 27 years after the patients had sustained their injuries.
Using imaging techniques called Dynamic Susceptibility Contrast-Enhanced and Diffusion Tensor Imaging (DTI) MR sequences, the researchers observed that HBOT increased blood flow and volume in the brain and that it led to the generation of new blood vessels. Using various cognitive tests, the researchers also found that HBOT improved memory, information processing speed, and executive functions.
Based on these findings, the researchers concluded that HBOT is beneficial for patients with TBI by inducing neuroplasticity in the brain, improving the integrity of microstructures of both white and gray matter within the brain, and allowing for the regeneration of nerve fibers. Future research will help clarify further benefits of HBOT and how the brain responds to this treatment.

Parkinson’s disease is known to be a slowly progressing neurological disorder that can cause issues with the motor movement of the body. Signs of Parkinson’s disease can include severe stiffness, loss of balance, and lethargy. Although there are no cures for the condition, symptoms can be slowed down. However, most of the prescribed drugs for Parkinson’s disease can decrease in effectiveness over the course of time. This led to some investigation from researchers to consider the role of exercise as a treatment option. Initial studies revealed that exercise does reduce the symptoms and slowed the progression of the condition.
According to a recent phase 2 study, intense treadmill exercise can potentially reduce the progression symptoms of Parkinson’s disease. In this study, researchers treated exercise as a treatment and tracked the safety and effectiveness of different levels of exercise. The study consisted of 128 people that had been diagnosed with Parkinson’s disease and were not taking any medications nor exercised. The aerobic capacity, heartbeats and the severity of the disease were tested for a baseline.
The patients were divided into three groups. Group 1 was asked to continue living their life in a normal manner. Group 2 was asked to implement exercise in which they would walk on the treadmill daily for 30 minutes, four times a week. The speed of the treadmill was manipulated to maintain the heart rate of the participants between 60 to 65 percent of their maximum heart rate. Group 3 was asked to also implement exercise for the same amount of time but their heart rate was maintained in the range of 80 to 85 percent of their maximum rates. The patients were under supervision for the initial month and then asked to continue exercising on their own.
At the end of the six-month study, Group 1 showed their symptoms progressed further. Group 2 showed their symptoms progressed but not as much as Group 1. Group 3 showed almost no progression in their symptoms after following a heavier exercise regimen as the other groups. This study concluded that higher intensity exercise helped in decreasing the symptoms by improving the neuronal blood supply. Improved blood flow helps with the overall health of the brain and slows down the deterioration of the body.
The findings from the study are quite encouraging for patients who are recently diagnosed or early in their symptoms to have great benefits from the heavy exercise program. However, it is advised to consult with your physician prior to starting an exercise plan to avoid injuries and ensure your safety.
