Characterization of hematopoietic potential of mesenchymal stem cells.

Mesenchymal and hematopoietic tissues are important reservoirs of adult stem cells. The potential of tissue resident mesenchymal stem cells (MSCs) to differentiate into cells of mesodermal and ectodermal lineages has been reported previously. We examined the hypothesis that adherent adipose tissue resident mesenchymal stem cells (ASCs) are capable of generating cells with hematopoietic characteristics.

Fluorescence in situ hybridization using an old world monkey Y chromosome specific probe combined with immunofluorescence staining on rhesus monkey tissues.

To date, there is no commercially available Y chromosome probe that can be used for fluorescence in situ hybridization (FISH) for the male rhesus monkey. We have recently generated a probe for FISH with high specificity to the short arm of the rhesus monkey Y chromosome. In this study, we further describe a method that keeps the integrity of tissue-specific antigenic structures for immunofluorescence staining subsequent to FISH on paraffin-embedded rhesus monkey tissues.
