Pluripotent lineage of CD133 stem cells isolated from human skin samples.

Indian J Exp Biol 2013 Feb;51(2):107-15

Skin stem cells are very important in cosmetics, pharmacological and regenerative medicine and burn cases. Foreskin samples surgically removed after circumcision from boys below 7 years were collected and primary epidermal cells were prepared by enzymatic and mechanical tituration method. Selecting CD133 (prominin-1) multipotent stem cell marker, enriched stem cells were analyzed by MACS using CD133 antibodies conjugated with magnetic beads. CD133 positive and negative cells with specific skin stem cells markers like - CD34 (Universal stem cells marker), CD29 (integrin beta-1) and CD49f (integrin alpha-6) immunophenotypes were screened and sorted in flowcytometer. Further the expression of four embryonic genes or transcription factors of pluripotent stem cells were analyzed for pluripotent character of sorted cells. It was found that skin stem cell markers associated with CD133 cells, differentially expressed CD34, CD29 and CD49f immunophenotyes on both positive and negative CD133 cells in FACS analysis. The embryonic stem cell markers (induced pluripotent stem cell markers) like Oct4, SOX2, Notch-2 and K19 genes were expressed in CD133 positive epidermal cells. It is therefore evident that foreskin derived epidermal stem cells showed pluripotent or multipotent nature. This finding opens up avenues for new uses of these stem cells for direct cell seeding in wound healing, surgical suturing and drug screening.

Neural stem cells & supporting cells--the new therapeutic tools for the treatment of spinal cord injury.

Indian J Med Res 2009 Oct;130(4):379-91

Care Hospital, The Institute of Medical Sciences, Hyderabad, India.

Stem cells play important role in the development and in the maintenance of specific tissues. They have been identified in majority of the organs like liver, blood, skin and intestine. Role of stem cells in regenerative medicine have been implicated in many chronic diseases. Stem cell research is a new opportunity to those patients whose organs are damaged or diseased. The discovery of stem cells in central and peripheral nervous system is relatively recent. Spinal cord injury is one of the major neurological disaster affecting mostly young lives. Stem cell transplantation in spinal cord injury patients have shown encouraging results. Different sources of stem cells are being exploited for spinal cord injury as well as other neurological disorders.
