Figure 1 (A–C) Preantral follicles stained with hematoxylin-eosin from frozen-thawed and vitrified-warmed fragments of ovarian tissue after 1 week of xenografting to nude mice: (A) primordial follicle from frozen-thawed tissue; (B) primary and secondary follicles from vitrified-warmed tissue (vitrification protocol 1); (C) primary and secondary follicles from vitrified-warmed tissue (vitrification protocol 2). (D–F) Ki-67 immunostaining: (D) positive staining in growing follicles from frozen-thawed grafted tissue; (E) positive staining in vitrified-warmed grafted tissue (vitrification protocol 1); (F) positive staining in and vitrified-warmed grafted tissue (vitrification protocol 2).

Figure 2 Hematoxylin-eosin (A) and Masson trichrome (B) staining on ovarian tissue after freezing, thawing, and xenografting. Fibrotic areas were evidenced by Masson trichrome strongly stained blue due to collagen fibers present in higher numbers among stromal cells.

Figure 3 Analysis of DNA strand breaks by TUNEL in grafted ovarian tissue. Pictures of DAPI counterstaining (cells in blue) and TUNEL staining (cells in red) are merged. Stromal cells in: (A) frozen-thawed tissue; (B) vitrified-warmed tissue (vitrification protocol 1); (C) vitrified-warmed tissue (vitrification protocol 2). Original magnification ×20.
