pubmed:abstractText |
The effect of the mitogen bombesin on pHi in cells of the chick otic vesicle was studied using dual wavelength micro-spectrofluorimetric techniques. The results show that the bombesin did not produce an immediate alkalinization in quiescent otic vesicle cells nor a long-term change in pHi in vesicles reactivated to grow in culture. The recovery of pHi from an acid load, caused by an NH4 pulse, involved both Na+/H+ exchange and Na+:HCO3 influx mechanisms, neither of which was influenced by bombesin. These observations do not fit with a general model whereby pHi is a universal signal for DNA replication and cell proliferation.
