Abstract:

The present study was performed to improve the process of tissue explant method and explore the cryopreservation method of bovine mammary gland.The mammary epithelial cells were isolated and cultured from the fresh and cryopreserved (8 mouths) mammary gland that collected from a 24 months’ Holstein dairy cow without history of lactation by tissue explant method including the side-place and inversion pattern respectively.Side-place method could shorten 1-2 days for appearance of cell,and improve the speed and adherence effect of tissue pieces,and the cells could climb out on the second day from the tissue pieces that were cultured and moved another flask.The survival rate was 50% for the tissue mass by liquid nitrogen storage followed by one-step cryopreservation (-80 ℃) with freeze-stored solution FBS∶DMSO∶DMEM/F12=7∶2∶1 while the survival rate was 56% with freeze-stored solution FBS∶DMEM/F12∶DMSO∶HEPES/sodium pyruvate=10∶7∶2∶1.The side-place method and tissue pieces recycling method were established for mammary epithelial cells culture in the presented study,which could shorten the cycle of tissue explant method.And the buffer HEPES/sodium pyruvate was benefit for maintaining the tissue bioactivity.
