High Power of Cap Stage
This is a higher magnification of the cap stage tooth bud seen in the preceding image (# 9). The knot of cells in the center of the field is composed of IDE cells (A) that bulge downward into the top of the dental papilla (B). This mass is referred to as the enamel knot (C). This is a transient structure that appears and disappears during the cap stage. There is no known functional significance attached to it. Also identify the ODE (D), stellate reticulum (E), dental lamina (F), dental sac/follicle (G), and cervical loop (H).
