Seventy-three samples of adipose tissue from 59 infants, aged from 25 weeks' gestation to 18 months of age, were obtained at necropsy, or at operations, or by needle biopsy. Adipose cell size was measured by microscopy. During fetal life the mean cell diameter increases from about 40 mum at 25 weeks' gestation to 50-80 mum at term. Adipose cells from the buttocks are larger than those from abdominal wall. After birth, adipose cell size continues to increase so that by 3 months the mean cell diameter is about 90 mum. Observations made on infants that had been born preterm showed that the growth of adipose cells proceeds at the same rate whether development in intrauterine or extrauterine.
从59名年龄在妊娠25周 至18个月的婴儿身上获取了73份脂肪组织样本,这些样本是在尸检、手术或经皮穿刺活检时采集的。通过显微镜测量脂肪细胞大小。在胎儿期,平均细胞直径从妊娠25周时的约40μm增加到足月时的50 - 80μm。臀部的脂肪细胞比腹壁的脂肪细胞大。出生后,脂肪细胞大小持续增加,到3个月时平均细胞直径约为90μm。对早产儿的观察表明,无论在子宫内还是子宫外发育,脂肪细胞的生长速度相同。
