Mouse follicles require the addition of gonadotropins (Gns) to complete maturation and ovulation of oocyte and antrum formation of follicles in vitro. However, we tried examination of in vitro growth of mouse pre-antral follicles in medium without Gns and physiological factors. And also, pre-antral follicles were isolated from ovaries by mechanical method. Our present studies were conducted to evaluate on the growth of follicles and intra-follicular oocytes and antrum formation in vitro of mouse pre-antral follicles in two different media. Pre-antral follicles (91-120${\mu}{\textrm}{m}$) were isolated mechanically by fine 30G needles not using enzymes from ovary of 3-6 weeks old female ICR mice. Isolated pre-antral follicles were cultured in 20 ${mu}ell$ droplets of TCM (n=17; follicles: 107.8 $\pm$ 1.58 ${\mu}{\textrm}{m}$; oocytes: 59.9$\pm$1.2 ${\mu}{\textrm}{m}$) or MEM (n=12; follicles: 109.3$\pm$2.53 ${\mu}{\textrm}{m}$; oocytes: 55.4 $\pm$1.6${\mu}{\textrm}{m}$) under mineral oil on the 60mm culture dish. All experimental media was supplemented with 10% FBS but without Gns and/or physiological factors. Pre-antral follicles were individually cultured in drops for 8 days. Antrum formation and growth of pre-antral follicles and intra-follicular oocytes were evaluated using a precalibrated ocular micrometer at $\times$200 magnifications during in vitro culture. Results between different groups were analyzed using combination of Student's t-test and Chi-square, and considered statistically significant when P<0.05. Antrum formation of pre-antral follicles had started in two culture media on day-2. On day-8, antrum formation had occurred in 58.3%(7/12) of pre-antral follicles cultured in MEM, but only in 23.5% (4/17) of those cultured in TCM (P=0.0364). Growth of pre-antral follicles and intra-follicular oocytes were observed on day-4 and -8. On day-4, follicular diameters was similar (P=0.1338) in TCM (119.4$\pm$2.58 ${\mu}{\textrm}{m}$) and MEM (125.4$\pm$4.52 ${\mu}{\textrm}{m}$). However, on day-8, diameters of pre-antral follicles cultured in MEM (168.9$\pm$17.29 ${\mu}{\textrm}{m}$) was significantly (P=0.0248) bigger than that in TCM (126.7$\pm$4.28 ${\mu}{\textrm}{m}$). On day-4 and -8, diameters of intra-follicular oocytes were similar TCM (67.1$\pm$1.3 and 72.4$\pm$0.9${\mu}{\textrm}{m}$) and MEM (65.2$\pm$1.7 and 73.3$\pm$1.5 ${\mu}{\textrm}{m}$), respectively. We can conform that medium not supplemented with Gns and/or physiological factors can be used for in vitro antrum formation and growth of mouse pre-antral follicles and intra-follicular oocytes. In conclusion, MEM supplemented with FBS can be used for growth in vitro of mouse pre-antral follicles isolated mechanically.
