CD44 and infection: To determine if the co-receptor role of CD44 and c-Met was intact in human tissue,hFGOs were infected with H. pylori G27 strain.Compared to the control treated (CON) hFGOs, infection with H. pylori triggered a significant induction in proliferating cellsthat was not seen in organoids injected with the ∆CagA mutant strain (Fig. 6A, B).
