Cryobanking of primary somatic cells of elite farm animals - a pilot study in domesticated water buffalo (Bubalus bubalis).

This study aimed to 1) establish and cryopreserve somatic cells from elite buffaloes, and 2) share stored somatic cells and their associated data with researchers. To achieve these targets, somatic cells were established successfully from tail-skin biopsies of 17 buffaloes. The informative data such as buffalo details (breed, date of birth, sex, and age at the time of tissue biopsy collection, and production traits), the number of cryovials stored, and freezing dates were recorded in an electronic file and a printed inventory record. The established somatic cells were flat, spindle-shaped morphology, and expressed vimentin (a fibroblast-like cell type marker) and the negative expression of cytokeratin-18 (an epithelial cell type marker). Altogether, we cryopreserved 970 cryovials (0.1 million cells per vial) from two buffalo breeds, namely Murrah and Nili-Ravi (at least 45 cryovials per animal), for cryobanking. Somatic cell nuclear transfer (SCNT) experiments demonstrated the utility of cryopreserved cells to produce cloned buffaloes. Importantly, these cryopreserved somatic cells are made available to scientific communities. This study encourages the cryopreservation of somatic cells of elite farm animals for their utilization in cell-based research.
