Proliferation and differentiation of SSCs after transplantation. Paraffin sections were prepared from the transplanted mouse testes. Immunofluorescence was used to detect the colonization, proliferation, and differentiation of the transplanted SSCs in the seminiferous tubules of the mice. The transplanted SSCs colonized and proliferated extensively in the basement of the seminiferous tubules of mice and differentiated into spermatogenic cells at various levels. Scale bar = 100 μm
