Figure 5From: Co-culturing of follicles with interstitial cells in collagen gel reproduce follicular development accompanied with theca cell layer formationRelationship between the horizontal and vertical diameters of cultured follicles. The horizontal line shows horizontal follicle diameters at day 5, and the vertical line shows vertical follicle diameters on day 5. Black square show follicles co-cultured with interstitial cells (n = 21) and white square show follicles cultured without interstitial cells (n = 7).Back to article page
