Tissue function depends on hierarchical structures extending from single cells (B10 lm) to functional subunits (100 lm– 1 mm) that coordinate organ functions. Conventional cell culture disperses tissues into single cells while neglecting higher-order processes. The application of semiconductordriven microtechnology in the biomedical arena now allows fabrication of microscale tissue subunits tha...

BACKGROUND This study was conducted to evaluate fibroblast co-culture and Activin A on in vitro maturation and fertilization of mouse preantral follicles. METHODS The ovaries from 12-14-day-old mice were dissected, and 120-150 μm preantral follicles were cultured individually in α-MEM as based medium for 12 days. A total number of 456 follicles were cultured in four conditions: (i) base mediu...

BACKGROUND The aim of this study was to evaluate fibroblast co-culture on in vitro maturation and fertilization of prepubertal mouse preantral follicles. MATERIALS AND METHODS The ovaries of 12-14 day old mice were dissected and 120-150 μm intact preantral follicles with one or two layers of granulosa cells, and round oocytes were cultured individually in α-minimal essential medium (α-MEM) su...

Background: To evaluate the imaging findings in patients with breast cancer diagnosed before age 40 and their correlation with histological type and molecular subtype. Methods: A descriptive, retrospective, single-center study was conducted by reviewing imaging exams and medical records, after approval of the institution’s Ethics Review Board. Among the 120 patients studied, 112 (93.3%) had mam...
