Abstract
The formation of intracellular glass may help protect embryos from damage due to desiccation. Soluble sugars similar to those found in desiccation tolerant embryos were studied with differential scanning calorimetry. Those sugars from desiccation tolerant embryos can form glasses at ambient temperatures, whereas those from embryos that do not tolerate desiccation only form glasses at subzero temperatures. It is concluded that tolerant embryo cells probably contain sugar glasses at storage temperatures and water contents, but intolerant embryo cells probably do not.
摘要
细胞内玻璃的形成可能有助于保护胚胎免受干燥引起的损伤。研究了与耐旱胚胎中发现的相似的可溶性糖，用差示扫描量热法进行了研究。那些来自耐旱胚胎的糖可以在环境温度下形成玻璃，而那些来自不耐受干燥的胚胎的糖只能在零下温度下形成玻璃。结论是，耐旱胚胎细胞可能在储存温度和含水量下含有糖玻璃，但不耐受胚胎细胞可能没有。
