It is believed that the signals that control hair follicle differentiation arise from cells in a structure called the dermal papilla. Understanding the nature of those signals is of interest for the biology of the normal tissue.  We have developed a technique for isolation of dermal cells by enzymatic digestion of intact skin. We have identified two subpopulations of cells that can be separated by FACS. The Sox2-positive CD133-positive cells are found exclusively in the dermal papillae of guard/awl/auchene hairs, while Sox2-negative, CD133-positive cells are found in the other hair follicle types. We compared these populations with unfractionated dermal cells.   We isolated the following 3 populations of cells from the back skin of neonatal mice (P2) by Flow Cytometry: 1) GFP-CD133- Total dermal cells 2) GFP-CD133+ Dermal Papilla cells 3) GFP+CD133+ Dermal Papilla cells The yield is approximately 50,000 cells of each population.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-16801", "species": "mouse", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-16801/samples/"}
