摘要: The rat lens undergoes dramatic growth during early postnatal development. Lens weight increased by a factor of 23 in 26 days. Growth rate per day oscillated between 0 and 87 percent. A new culture system was designed to study the oscillations transparency vitro required pulsatile delivery platelet-derived (PDGF) HL-1 serum-free medium. Continuous medium with PDGF or without resulted opacity no growth. These results provide direct evidence that stimulates an epithelial tissue occur normal development lens.
