The development of simple branched tubular glands involves several stages:
1. Bud Formation: The process begins with the formation of epithelial buds from the surface epithelium. 2. Branching Morphogenesis: The epithelial buds undergo branching, forming multiple tubular structures. 3. Differentiation: The cells within the tubular structures differentiate into specific cell types, such as mucous, chief, and parietal cells, based on their location and function.
