After 7 days in floating culture, emergent EBs were transferred onto gelatin-coated 6-well culture plates and were maintained in primate ESC culture medium without bFGF at 37 °C under humidified atmosphere of 5%% CO2.
in vitro spontaneous differentiation of patient-derived iPSCs into EB-mediated three germ layers was performed as follows: Briefly, cultured and harvested patient-derived iPSCs were transferred onto ultra-low-adherent culture dishes (HydroCell; CellSeed) and were maintained in primate ESC culture medium without bFGF at 37 °C under humidified atmosphere of 5%% CO2.
Characterization of patient-derived iPSCs via detection of pluripotency markers was performed as follows: Briefly, cultured and harvested patient-derived iPSCs were transferred onto MEF-seeded 6-well culture plates and were maintained in primate ESC culture medium at 37 °C under humidified atmosphere of 5%% CO2.
Retinas were maintained in culture for several days by using a procedure we optimized for mouse and primate fetal retinas (see Methods).
In primates, relationships are maintained by grooming a small set of key allies, but the amount of time primates can devote to grooming is limited by competing demands for time (Dunbar et al. 2009).
ABO variation in primates is unlikely to be maintained by this mechanism, however, given that there exist haplotypes encoding the AB phenotype (" cis-AB" alleles), which are fixed in Mus musculus for instance 15, and yet these are found only at very low frequencies in humans and have not been reported in other primates 6.
This study also indicates that human malaria parasite has been maintained in nonhuman primates in a nonendemic country, which has significance to public health issues.
In contrast, yellow fever virus, which is maintained by nonhuman primates, has a more geographically structured phylogeny (39 ).
Thus, it is likely that placental genomic imprinting of DNMT1 is maintained throughout the primate lineage.
Primates were anesthetized with ketamine, and anesthesia was maintained with 2%to3%3% isoflurane in 100% oxygen.
