Which of the following gastric cells indirectly help in erythropoiesis?

Parietal cells are the gastric cells that indirectly help in erythropoiesis. Parietal cells secrete both HCl and Castle’s intrinsic factor. Castle’s intrinsic factor is required for absorption of vitamin B₁₂. This vitamin is required for maturation of RBCs and thus plays an important role in erythropoiesis (production of erythrocytes).
