For this purpose, we study (1) the normal distribution of CD34+SCs/TCs in the different layers of the gallbladder and colon, and (2) the stromal cell response during repair in these organs, including the following processes (a) acute cholecystitis with initial and specific repair phenomena, (b) surgically resected segments of the colon after endoscopic resection of malignant polyps and India ink tattoos, leading to macrophage infiltration and stromal cell reaction, and (c) infiltrating colon adenocarcinomas with an important stromal reaction (desmoplastic reaction). This evidence concerns the gene CD34 and colon adenocarcinoma.
