This protocol describes the primary culture/co-culture of mouse ovarian tissue, using ovaries from neonatal mice and individual ovarian follicles from prepubertal mice. The culture techniques support development in a highly physiological manner, allowing investigation of the effect of extrinsic agents on the ovary, and of interactions between ovarian follicles.

A highly promising technique to generate tissue constructs without using matrix is to culture cells in a simulated microgravity condition. Using a rotary culture system, we examined ovarian follicle growth and oocyte maturation in terms of follicle survival, morphology, growth, and oocyte function under the simulated microgravity condition.

The hair follicle is a highly complex appendage of the skin containing a multiplicity of cell types. The follicle undergoes constant cycling through the life of the organism including growth and resorption with growth dependent on specific stem cells. The targeting of the follicle by genes and stem cells to change its properties, in particular, the nature of the hair shaft is, discussed. Hair follicle delivery systems are described, such as liposomes and viral vectors for gene therapy. The...
FAQs
They act as protective solutes during cooling by replacing or managing cellular water and helping the sample reach a glass-like state rather than forming damaging ice. Their high concentration is important because vitrification depends on rapid solidification without crystallization. In follicle preservation, this protection helps retain the follicle’s organization for subsequent warming and biological assessment.
Extremely rapid cooling limits the time available for water molecules to organize into ice crystals. That matters because crystallization can damage cellular structures within the follicle. Instead, the cryoprotective solution and cooling conditions promote a glass-like state. The result is preservation focused on reducing physical injury during storage, rather than allowing conventional ice formation.
Maintaining follicular structure is important because the follicle is not merely a container for an immature oocyte. Its organization and cellular interactions provide a model for examining folliculogenesis and ovarian function. Preserving those relationships allows researchers to study how follicles survive, grow, and support oocyte development after warming, rather than evaluating isolated cells alone.
After warming, follicles can be placed in culture so their biological performance can be examined. Researchers may assess whether the follicles survive, continue growing, and support oocyte development. These observations provide functional information that is not available from storage alone, helping connect the preservation step with studies of folliculogenesis, ovarian function, and reproductive technologies.
The technique provides a potential way to store ovarian follicles for later use when researchers or fertility-preservation programs need access to reproductive material. Its value is especially relevant when conventional tissue preservation is unsuitable. Subsequent warming and culture can help determine whether preserved follicles remain viable and retain properties useful for reproductive research or fertility-related applications.
Preserved follicles can serve as controlled models for investigating ovarian biology after storage and warming. Because the method aims to retain follicular organization and cellular interactions, researchers can examine processes connected with folliculogenesis, ovarian function, and oocyte development. This makes the approach useful for studying reproductive technologies while keeping the follicle’s multicellular context intact.
