Deer antler stem cells are a novel type of cells that sustain full regeneration of a mammalian organ—deer antler

a Cells from antler relative tissues were isolated and cultured as described in methodology section; their morphology was monitored under microscope (Passages？≤？5); Bar？=？100？μm. b Colonies formed after seeding 100 cells/well at day 14, and were stained with crystal violet dye; Bar？=？5？mm; APC antlerogenic periosteal cell, PPC pedicle periosteal cell, RMC reserve mesenchymal cell, BMSC bone marrow stem cel
