Three-dimensional Matrigel constructs contained aleolar forming units comprised of cells displaying AE2 cellular ultrastructure while expressing the SpC gene and gene product. The addition of tissue-specific growth factors induced formation of branching, sacculated epithelial structures reminiscent of the distal lung architecture.

通过对细胞亚微结构的观察和对SpC基因及其表达产物的分析，研究者发现培养体系中肺组织形成单位中具有能向肺泡II型上皮细胞分化的细胞；而通过添加组织特异性的生长因子，他们还发现这一做法会促进培养组织形成具有分支和囊状上皮结构的类似终末肺泡组织的形态结构。
