Figure 7From: Differential expression of a BMP4 reporter allele in anterior fungiform versus posterior circumvallate taste buds of miceProliferating and mitosing cells are basal epithelial and perigemmal cells in both fungiform and circumvallate taste papillae. Proliferating PCNA-IR cells (red) and mitosing pH3-IR cells (green) in the circumvallate (A) and fungiform papillae (B) are located perigemmally, and not inside taste buds (white dashed outlines). Scale bars: 50 μm.Back to article page
