I want to perform Leydig cell isolation from testis. How many months I can preserve rat testis for viable Leydig cells and what kind of media can be used for the preservation?
If you freeze the whole testis, I do not think any cell be alive. If you isolate the cells and use proper cryopreservation medium- like 10% DMSO with some serum and than freeze at -80 by using slow freezing (like 1C/min) Or using some freezer devices, your question can be valid. That is just my opinion. You may wait answer from other researchers.
