Which of the following is a true statement about hair development? (Check all that apply) A At telogen, dermal fibroblasts secrete BMP4, which inhibits the proliferation of HFSCS. At telogen, cells are actively proliferating in the inner bulge layer. At telogen, BMP6 and FGF18 from the inner bulge layer promote the apoptosis of HFSCS. At telogen, subcutaneous fat cells secrete BMP2, which inhibits the proliferation of HFSCS. E At telogen-to-anagen transition, fat cells precursors produce PDGF-alpha, which induces the dermal papilla to produce other factor F) At telogen-to-anagen transition, dermal fibroblasts secrete Wnts, which promote the proliferation of HFSCS. G At telogen, stem cells are actively proliferating. H) At anagen, stem cells are all quiescent. At telogen-to-anagen transition, stem cells become activated. At catagen, most of the outer root sheath undergoes apoptosis.
