Chinese Hamster
The Chinese hamster is a rodent in the genus Cricetulus of the subfamily Cricetidae that originated in the deserts of northern China and Mongolia. They are distinguished by an uncommonly long tail in comparison to other hamsters, most of whose tails are stubby.

中国仓鼠 原产于中国北部沙漠地带。20世纪初，中国科学家首次将中国仓鼠作为生物实验动物使用。20世纪中期，美国科学家开始使用中国仓鼠做实验。1957年，美国科罗拉多大学的科学家从一个雌仓鼠的卵巢中提取细胞，并在体外培养细胞。由于中国仓鼠有着特殊的基因构成，中国仓鼠卵巢细胞在体外很容易大量繁殖，从1980年代开始，把重组基因植入仓鼠卵巢细胞(CHO cell，即Chinese Hamster Ovary)已经成为生产抗体药物的生产手段。

👁形貌
Chinese hamsters grow to between 82 and 127 mm in body length (tail length 20–33 mm) and weigh 1.7 grams at birth, then as they get older can weigh 30–45 grams. Males have a fairly large scrotum relative to their body size. Their body proportions, compared to other hamster species – most of which tend to be compact – appear "long and thin" and they have (for a hamster) a relatively long tail. They live two to three years on average. The wild color is brown with a black stripe down the spine, black and grey ticks and a whitish belly. This coloration, combined with their lithe build and longer t
