Outline of Final Research Achievements |
Mesenchymal cells were extracted and cultured from skin of newborn C57BL/6J mice, and each cell spheres were made using serum-free medium on non-adhesive culture dishes. Spheres were viable for the comparative long term of the months unit in spite of the non-adhesive condition, which suggest the possibility that the spheres were in so-called hibernation state. In genetic and immunohistological examination, the Wnt related markers which supposed to concerned with hair follicle regeneration and hair cycle, and also the undifferentiated markers such as Sox-2, Oct-4, CD133, cxcr4 were seen to relatively upregulated after forming the cell spheres. But the distribution of the markers was not equal in cell spheres, it is necessary to examine whether it is the result of character change in some specific cells or the result of the cell choice.
