In dogfish, spermatogenesis progresses from a restricted germinative zone, which lines the dorsal testicular vessel. Single spermatogonia (A(s)), including the spermatogonial stem cells (SSCs), produce successively paired (A(p)), undifferentiated (A(u4) to A(u512)), and differentiated (A(d1) to A(d8)) spermatogonia and preleptotene (PL) spermatocytes(More)
Liver failure is an increasing problem. Donor-organ shortage results in patients dying before receiving a transplant. Since the liver can regenerate, alternative therapies providing temporary liver-support are sought. A bioartificial-liver would temporarily substitute function in liver failure buying time for liver regeneration/organ-procurement. Our aim:(More)
Acute liver failure has a high mortality unless patients receive a liver transplant; however, there are insufficient donor organs to meet the clinical need. The liver may rapidly recover from acute injury by hepatic cell regeneration given time. A bioartificial liver machine can provide temporary liver support to enable such regeneration to occur.

Previous work in dogfish, Scyliorhinus canicula, has identified the testicular germinative area as the spermatogonial stem cell niche. In the present study, an in vitro co-culture system of spermatogonia and somatic cells from the germinative area was developed. Long-term maintenance of spermatogonia has been successful, and addition of GDNF has promoted(More)
