Novel Engraftment and T Cell Differentiation of Human Hematopoietic Cells in SCID Pigs.

Pigs with severe combined immunodeficiency (SCID) are an emerging biomedical animal model. Swine are anatomically and physiologically more similar to humans than mice, making them an invaluable tool for preclinical regenerative medicine and cancer research. One essential step in further developing this model is the immunological humanization of SCID pigs.

A critical analysis of quantitating flow cytometry: the role of the crossmatch in 2014.

The mean fluorescent intensity obtained using single antigen beads does not represent the titer of the serum sample very well because the degree of saturation of the antigen on the bead varies by individual bead and the human leukocyte antigen antibody-binding site on the bead may not duplicate the activity of the serum's antibodies in vivo. The flow crossmatch appears to come closer to correlating with the titer. As we have shown, the titer will roughly correlate with the flow crossmatch.
