BARBOSA, A.P.M.; MARTINS, C.F.  e  SERENO, J.R.B.. Cryopreservation of bovine spermatogenic cells using different protective molecules. Arch. zootec. [online]. 2011, vol.60, n.230, pp.293-296. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922011000200014.

The objective of this study was to isolate mechanically bovine spermatogenic cells and assess their viability before and after cryopre-servation with three different cryoprotector molecules. The isolated cells presented an initial viability of 76.5%; after cryopreservation it was 51.7%, 55.5% and 58.8%, respectively for solutions with DMSO, propanodiol, and DMSO with propanodiol. The solution of DMSO with propanodiol was significantly better (p<0.05) than that with only DMSO, for preserve the cellular viability. Thus was possible to verify that spermatogenic cells isolated mechanically can be cryopreserved-thawed with larger viability than 55% in the solutions contends propanodiol. The cells frozen with the association of DMSO and propanodiol presented the largest integrity rate after the thawed, and can be applied in studies with ICSI.
