Scientists at Sanford Burnham Prebys Medical Discovery Institute have created a drug that can lure stem cells to damaged tissue and improve treatment efficacy—a scientific first and major advance for the field of regenerative medicine. The discovery, published in the Proceedings of the National Academy of Sciences (PNAS), could improve current stem cell therapies designed to treat such neurological disorders as spinal cord injury, stroke, amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders; and expand their use to new conditions, such as heart disease or arthritis.

The American Academy of Orthopaedic Surgeons (AAOS) continues to demonstrate its commitment to advancing the quality of musculoskeletal care in a fully transparent and scientific way. Debuting today as a new member benefit, the AAOS Biologics Dashboard is a dynamic online tool designed to help orthopaedic surgeons navigate the approval status of biologic-based interventions. The development of the AAOS Biologics Dashboard is just one of several efforts within the Academy’s Biologics Initiative that offers evidence-based guidance to the musculoskeletal health community. An additional effort is the revision of two biologics-related position statements, recently approved by the AAOS Board of Directors.

DALLAS – Oct. 12, 2020 – By far, the most common injuries seen in emergency rooms in the United States are those affecting extremities. Immobilization is the most common treatment, and yet, until recently, it was unknown exactly why this technique worked to advance healing.
Research in pigs shows that using the exosomes naturally produced from a mix of heart muscle, endothelial and smooth muscle cells — all derived from human induced pluripotent stem cells — yields regenerative benefits equivalent to the injected human induced pluripotent stem cell-cardiac cells.
Imagine this: A patient learns that they are losing their sight because an eye disease has damaged crucial cells in their retina. Then, under the care of their doctor, they simply grow some new retinal cells, restoring their vision.
Although science hasn’t yet delivered this happy ending, researchers are working on it – with help from the humble zebrafish. When a zebrafish loses its retinal cells, it grows new ones. This observation has encouraged scientists to try hacking the zebrafish’s innate regenerative capacity to learn how to treat human disease. That is why among the National Eye Institute’s 1,200 active research projects, nearly 80 incorporate zebrafish.
University of Wisconsin–Madison researchers demonstrated a proof-of-concept stem cell treatment in a mouse model of Parkinson’s disease. They found that neurons derived from stem cells can integrate well into the correct regions of the brain, connect with native neurons and restore motor functions.

Surgeons at Mass Eye and Ear have replaced the ocular surface of four patients who each experienced chemical burns to one eye by using their own stem cells taken from the other healthy eye, in a technique known as “cultivated autologous limbal epithelial cell transplantation” (CALEC). These four cases, all part of an ongoing clinical trial supported by the National Eye Institute of the NIH, represent the first procedures of their kind to occur in the United States.

In one of the first studies addressing the role of sex hormones’ impact on stem cells in the gut, scientists outline new insights showing how a steroidal sex hormone that is structurally and functionally similar to human steroid hormones drastically alters the way intestinal stem cells behave, ultimately affecting the overarching structure and function of this critical organ. The authors found that ecdysone, a steroid hormone produced by fruit flies, stimulates intestinal stem cell growth and causes the gut of the female fruit fly to grow in size, as well as other critical changes.
