Figure 1From: Three dimensional culture of fresh and vitrified mouse pre-antral follicles in a hyaluronan-based hydrogel: a preliminary investigation of a novel biomaterial for in vitro follicle maturationMorphology of metaphase II oocytes and live imaging of meiotic spindles in oocytes derived from HA- embedded follicles (3 mg/ml), cultured for 12 days before exposure to hCG and EGF. (A-D). Oocytes imaged at 300X magnification using the Oosight Imaging system . (C, D), Spindles showed moderate to high retardance, suggestive of a well organized and ordered structure.Back to article page
