Morphometrical analyses of secretory tubules of baffle zone and tendril components in the secretory lumen. Changes in areas of tendril components (A) and secretory tubules (C) following the P4 implantation. Strong positive correlation was found between the tendril diameter and the area of tendril components (B), while only moderate correlation was observed between the tendril diameter and the area of secretory tubules (D); open squares, P4 implantation for 1 day; filled circles, P4 implantation for 2 days using 8 cm tubing; open triangles, P4 implantation for 5 days; open circles, P4 implantation for 2 days using 2 cm tubing; cross marks, E2 implantation for 2 days (one individual formed tendrils). Different letters denote significant differences (P < 0.05)
