Histomorphometric and scanning electron microscopic analysis were performed on 74 embryos and foetuses and on 20 sheep (early post-natal to adult age). Histodifferentiation of the reticulum took place at 33 days of foetal life. Reticular ribs were observed as evaginations of the epithelial stratum germinativum at 64 days. Neutral mucopolysaccharides first appeared in epithelial cells at 46 foetal days, thereafter to decrease gradually in number, subsequently stabilising in postnatal life. Acid mucopolysaccharides, mucins and mucoid compounds were not detected. Growth curves and formulae were constructed for each tissue layer. Initial test involved multiplicative (y = axb), linear (y = a+bx) and polynomial model (y = a+b+cx2+dx3).
对74个胚胎和胎儿以及20只绵羊（出生后早期至成年期）进行了组织形态计量学和扫描电子显微镜分析。网状组织的组织分化在胎儿期33天时发生。在64天时，网状嵴被观察为生发上皮层的外翻。中性粘多糖在胎儿46天时首次出现在上皮细胞中，此后数量逐渐减少，随后在出生后生活中稳定下来。未检测到酸性粘多糖、粘蛋白和类粘液化合物。为每个组织层构建了生长曲线和公式。初始测试涉及乘法模型（y = axb）、线性模型（y = a + bx）和多项式模型（y = a + b + cx2 + dx3）。
