Regenerative medicine seeks to restore the functionality of cells, tissues, organs, or genes. In particular, stem cell therapy is among the most promising forms of regenerative medicine. This is due to the fact that stem cells are not specialized cells and can, therefore, transform into any cell or tissue with which they come into contact, including that of muscle, tendon, bone, and ligament. From supporting regrowth of meniscal cartilage in the knee to the self-renewal of central nervous system (CNS) tissue, stem cell therapy has shown a potential option of treatment for a broad range of conditions and injuries.
Stem cell therapy is an emerging regenerative medicine option for those who have sustained the central nervous system (CNS) damage including traumatic brain injury, stroke, and neurodegenerative disorders such as multiple sclerosis. CNS injury is characterized by an inflammatory response, molecular imbalance, cell death, and cyst and scar formation. Researchers suggest that co-therapies, such as physical rehabilitation, could help be a potential booster for their stem cell therapy treatment outcome.
Studies have shown stem cells’ ability to aid in CNS recovery but may also suggest that while significant improvement is made, the treatment is often not enough to completely recover CNS functionality without further intervention. In conjunction with physical therapy, stem cell therapy could produce stronger results. Targeted exercises can produce beneficial effects at the anatomical and physiological levels, thereby positively influencing neural stem cell pools and improving stem cell therapy outcomes. Exercise has been shown to augment stem cell transplantation following muscular injuries in certain studies, but further research is needed to determine exactly how physical therapy and stem cell treatments can be used to support optimized recovery on a case-by-case basis.
Moving forward, it is suggested that physical therapy could help as a supplement to stem cell therapy. By partnering these two therapeutic approaches, patients may be able to potentially improve their treatment outcomes as well as enhancing functionality and quality of life.

Perinatal stem cells have been attracting attention globally in recent years due to their potential in regenerative medicine. These stem cells come in many forms, due to the wide variety of potential sources for these cells. Perinatal stem cells, for instance, may be umbilical cord-derived hematopoietic stem cells, amniotic epithelial cells, amniotic fluid stem cells, or chorionic mesenchymal stem cells. All sources, nonetheless are considered biological waste and are therefore usually discarded after delivery of babies.
Importantly, perinatal stem cells, despite their origin, tend to share a number of characteristics that make them beneficial in treating conditions. Additionally, unlike other sources of stem cells, retrieval of perinatal stem cells is noninvasive and does not require the ethical considerations that retrieval from other sources may involve. A recent review in Regenerative Medicine has highlighted the potential benefits of perinatal stem cells in therapeutic interventions.
In addition to the relatively easy collection and preparation of perinatal stem cells, these cells tend to be easily harvested and manipulated without harming either the mother or the baby. Upon collection, these stem cells exist in high volume and have greater ability to proliferate than other stem cell types such as bone marrow stem cells. Research has also shown that these cells tend not to lead to adverse immune reactions, though the mechanisms involved in their relationship to the immune system are not well understood.
Given their relative advantages over other stem cell types, perinatal stem cells are well poised to be used in cell-based therapies targeting a wide variety of conditions. Future research will help to define the precise role these cells can play in regenerative medicine and which conditions they may be most useful for.

Although all living organisms experience aging, scientists have relatively little understanding of why aging occurs. The leading theories on aging suggest that living creatures sustain damage to their DNA through exposure to ultraviolet light, toxins, or even the day-to-day stresses of using oxygen for our cellular metabolism. Whatever the cause, this DNA damage causes cells to 1) repair themselves, 2) die, or 3) enter a middle state called senescence where they remain alive, but simply stop participating in active living. If cells successfully repair themselves, they don’t perceptibly age. If cells enter senescence or die, the body shows signs of aging.
The bottom line: If we can help cells repair themselves, and replace dying and senescent cells, we can slow or even reverse aging. All of this may be possible through the careful use of stem cells.
As we age, stem cells lose the ability to renew themselves, to become other cells (differentiate) and to replace aged cells. Older stem cells secrete less and less of the substances that help the cells around them stay young and healthy. Not only do our regular cells age, but so do our stem cells. This is perhaps the strongest point for using stem cells to reverse the visible signs of aging.
Adipose-derived stem cells are one of the most promising sources of stem cells for anti-aging and regenerative medicine. They are easy to harvest by liposuction to remove stem cells along with fat cells. In addition, adipose-derived stem cells have the potential to become all cell types in the skin; namely fat cells, skin cells, muscle cells, and fibroblasts, and others. Even if the stem cells do not become other cells, they strongly secrete cytokines and other substances that help renew and replenish the cells around them.
While additional research is required, adipose-derived mesenchymal stem cells are currently being tested in clinical trials to treat a number of age-related conditions. Indeed, clinicians are currently using the stem cells to perform a number of aesthetic procedures such as breast or buttock augmentation, hand rejuvenation, as facial dermal fillers, and to promote and restore hair growth. As we learn more about how to use the power of stem cells in aesthetic procedures, we will be able to better address the visible signs of aging in the face and body.

Multiple sclerosis (MS) has widespread effects on the body. The disease is characterized by a breakdown of the protective cover surrounding the nerves, called the myelin sheath. When the myelin sheath is compromised, it makes it more difficult for the brain to communicate critical messages to the rest of the body. Unfortunately, the ways in which MS affects the body are rarely isolated: when nerve cells are damaged as a result of myelin sheath damage, it leads to a disconnection between the brain and the organs, muscles, and tissues.
Muscle Weakness & Pain
Muscle weakness can impede daily life, and for some, it turns even basic tasks into obstacles. Weakness is often reported by MS patients in the limbs, which can make it difficult to walk, shower, and get dressed. It’s also the culprit behind foot drop, in which the front part of the foot cannot be lifted. This causes individuals to adjust their gait, such as swing their leg outward.
Beyond weakness, MS also often produces muscular pain. Many people with MS experience a sensation of “pins and needles,” sharp pain, tingling, or aches. Involuntary muscle spasms are also common and are experienced primarily in the legs.
Treatment Options
While options such as nerve-blocking agents, muscle relaxants, and pain relievers may be prescribed to treat severe muscle spasms or pain, many patients choose to explore non-drug alternatives first. Working with an occupational therapist, for example, can aid people with muscle pain or weakness in developing different approaches for completing daily tasks and conserving energy. Physical therapists, too, can provide targeted exercises to strengthen key muscle groups, which could help to combat muscle weakness or pain. Lastly, lifestyle adjustments such as improved sleep habits, rest breaks, and assistive devices could help you navigate the muscular challenges presented by MS. Stem cell therapy may also be an alternative option those with MS may consider to potentially help in managing some of the symptoms associated with MS.

Bone generally develops via one of two distinct mechanisms: intramembranous ossification and endochondral ossification. In the former case, mesenchymal progenitor cells directly differentiate into osteoblasts that form bone. In the latter case, the mesenchymal progenitor cells first create a matrix of cartilage that then acts as a template to enable the remodeling or development of bone tissue. This process of endochondral ossification is the predominant way that bone is generating during the healing process after bones are broken and fractures are endured. Using stem cells to facilitate this process can, therefore, be beneficial in non-healing bone fractures.
A new study published in Acta Biomaterialia has proposed that adipose tissue can be used in bone generation as a scaffold on which adipose mesenchymal stem cells can expand and allow for endochondral ossification. The researchers showed how adipose tissue could be used in this way, through what they termed Adiscaf, to successfully generate cartilage tissue and eventually bone tissue formation. The bone tissue that formed through this process contained bone marrow elements, further demonstrating the bone’s integrity and the promise of this procedure.
Compared to other strategies for building scaffolding, this strategy appeared successful because by using adipose tissue, the adipose stem cells were exposed to their native environment and therefore likely maintained functions they otherwise may not have. Not only will these findings help to solidify our understanding of how to nurture stem cells and enable them to differentiate in ways that can be therapeutically applicable, but they also specifically show how adipose tissue may be able to be used to generate a bone organ through endochondral ossification. Future research will likely help to clarify how these findings can be applied to patients to improve bone healing.
