Abstract Embryonic stem cells are pluripotent cells, capable
of differentiating into various cell types. In the
present study, feeder cell-free culture of midblastula
embryos of the Goldfish (Carassius auratus)
was carried out. Embryonic stem cells were derived
from mid-blastula stage embryos using pronase to
release the inner cell mass (ICM). The cells were
cultured in Leibovitz-15 medium on gelatin-coated
cell culture well plates supplemented with 15% fetal
bovine serum, 1% goldfish serum, basic fibroblast
growth factor and leukaemia inhibitory factors (LIF)
and were incubated at 28°C. The ES-like cells were
characterized by their unique round and polygonal
morphology, elevated activity of alkaline phosphatase,
spherical three-dimensional embryoid body
formation, chromosomal diploid number (2n=50).
The expression of Oct4, a member Oct family of
POU transcription factors, which play a key role in
regulating stem cell pluripotency and differentiation,
was used for characterization of undifferentiated
pluripotent ES cells. The expression of Oct4 in
embryonic stem-like cell (2nd passage) and gonads
of goldfish was studied by RT- PCR. Embryonic
stem-like cells culture from the mid blastula embryo
of C. auratus would be a useful tool for cellular
development and differentiation studies.
