Table 1 Quantification of bull-derived CD34+ cells in the livers of bovine triplet fetuses. Proportions of Y-chromosome positive (Y+) cells among liver CD34+ cells in the 60-day fetuses are shown, as detected by in situ hybridization. fm = freemartin, n = number of image fields analyzed.

From: Direct observation of hematopoietic progenitor chimerism in fetal freemartin cattle
