Thymus cellularity in Cx43+/+ or Cx43+/− mice after bone marrow transplantation.

(A) The transplantation protocol. (B) Thymus celllularity in Cx43+/+ or Cx43+/− recipients of Cx43+/+ or Cx43+/− bone marrow cells. (C) PCR analysis of testes, bone marrow (BM), and thymus (THY) from Cx43+/+ or Cx43+/− mice grafted with either Cx43+/+ or Cx43+/− bone marrow cells as indicated. Testis DNA was used to confirm the identity of the recipient mouse. Note that the genetic composition of the thymus of Cx43+/− mice that received Cx43+/+ bone marrow is not completely donor derived. Only 2 of 3 to 4 mice from each group are shown. The asterisk indicates values significantly different at P < .05.
