31. Most notably, the genes coding for the Major Histocompatibility Complex ( MHC class I and II genes. 32. Depending on the antigen and the type of the histocompatibility molecule, different types of T cells are activated. 33. However, these problems associated with histocompatibility may be solved using autologous donor adult stem cells, therapeutic cloning. 34. The expression of this protein is required for the transcription of a subset of class II major histocompatibility genes. 35. Women prefer men with major histocompatibility complex ( MHC ) genotypes and odor different from themselves especially during ovulation. 36. "The histocompatibility test showed that the concurrence between my sister's tissues and mine was rather low. 37. Histocompatibility and histocompatibility testing is most relevant for topics related to whole organ, tissue, or stem cell transplants.38. Histocompatibility and histocompatibility testing is most relevant for topics related to whole organ, tissue, or stem cell transplants. 39. This is the reason the organs would have to be altered to fit the patients'DNA ( histocompatibility ). 40. At the same time, individuals display disassortative mating for genes in the major histocompatibility complex region on chromosome 6.
