In a recent study conducted by the University Of Texas Southwestern Medical Center, scientists have discovered a rare line of stem cells involved in regulating spermatogenesis [the production of sperm cells]. Furthermore, these stem cells are resistant to chemotherapy and radiotherapy, which are toxic to the male germline and common causes for male infertility.
Advances in regenerative medicine, spearheaded by AFIRM [Armed Forces Institute of Regenerative Medicine], are restoring function to wounded soldiers. A consortium of research centers is developing techniques to grow body parts, such as ears, bones, skin and genitals. AFIRM is directing 300 million dollars to develop a broad array of regenerative treatments that will impact treatment options for both wounded soldiers and the general population. Many of the treatments are now entering the clinical [human] testing phase with the prospect of growing organs and tissue ‘on demand’ utilizing the patient’s own stem cells on the horizon.
