NFAH cryopreservation study. Samples were analyzed before (NFAH) and after (Cryo-NFAH) cryopreservation to check the integrity of the structure. (A) Explanatory scheme of the study. (B) Representative macroscopic images of samples. (C) Representative microscopic images of hematoxylin–eosin stained samples at ×40, ×100 and ×400 magnifications. (D) Porosity of the hydrogels. (E) Scanning electron microscopy analysis at ×1600; ×6000 and ×12,000 magnifications. (F) In vitro coagulation time assay.
