The intracellular composition of the avian shell gland mucosa was studied at six stages of egg formation. 2. Total water content of the mucosa before shell calcification was 4-8 kg/kg dry weight (dw) and rose to 6-6 kg/kg dw during shell formation; 60% of the increase was intracellular and 40% extracellular. 3. The potassium concentration of the mucosa remained constant during egg formation. 4. Chloride was removed constantly from the mucosal cells during egg formation. 5. A model was constructed for the glandular cells which depicts them as primarily NaHCO3-secreting cells towards the luminal side and HCl-secreting cells towards the serosal side, their main function being to provide CO2/3- for shell formation. In this model, the columnar mucosal cells are responsible for the calcium used in shell formation.
在蛋形成的六个阶段对禽蛋壳腺黏膜的细胞内成分进行了研究。2. 壳钙化前黏膜的总含水量为4 - 8千克/千克干重（dw），在壳形成过程中升至6 - 6千克/千克干重；增加量的60%为细胞内增加，40%为细胞外增加。3. 黏膜的钾浓度在蛋形成过程中保持恒定。4. 在蛋形成过程中，氯离子不断从黏膜细胞中去除。5. 构建了一个腺细胞模型，该模型将它们描述为朝向管腔侧主要分泌碳酸氢钠的细胞和朝向浆膜侧分泌盐酸的细胞，其主要功能是为壳形成提供二氧化碳/碳酸根。在这个模型中，柱状黏膜细胞负责壳形成中使用的钙。
