Chimeric mice derived from human--mouse hybrid cells

Chimeric mice derived from human-mouse hybrid cells.

Mouse teratocarcinoma cells from the OTT6050 ascites tumor were established in tissue culture and selected for 5-bromodeoxyuridine (BrdUrd) resistance. The embryonal carcinoma cells grew without a feeder layer, remained deficient for thymidine kinase (EC 2.7.1.75), and differentiated like the original tumor into various tissues after subcutaneous injection into 129 mice. We fused the BrdUrd-res...

Xenogeneic gene expression in chimeric mice derived from rat--mouse hybrid cells.

Thymidine kinase-deficient OTT6050 mouse teratocarcinoma cells were fused with hypoxanthine phosphoribosyltransferase-deficient Fu5AH rat hepatoma cells by means of inactivated Sendai virus. The resulting hybrid cells, which were selected in hypoxanthine/aminopterin/thymidine medium, retained almost all of the mouse chromosomes and various numbers of rat chromosomes, and showed many chromosomal...

Human Adipose-Derived Stem/Stromal Cells from Children or Adults?

Discovering a cell type with the highest efficiency and the least side-effects is one of the priorities of scientists active in this field. Of all the cells, mesenchymal stem cells have been and still are of interest to the researchers for use in pre-clinical and clinical studies due to being easily accessible, pluripotency, secretion of numerous growth factors, low risk of immunological reject...

Humanized neuronal chimeric mouse brain generated by neonatally engrafted human iPSC-derived primitive neural progenitor cells.

The creation of a humanized chimeric mouse nervous system permits the study of human neural development and disease pathogenesis using human cells in vivo. Humanized glial chimeric mice with the brain and spinal cord being colonized by human glial cells have been successfully generated. However, generation of humanized chimeric mouse brains repopulated by human neurons to possess a high degree ...
