組織再生研究のプラットフォームとしてのヒト卵巣表面上皮オルガノイド

Overview

This protocol outlines the establishment of three-dimensional (3D) tissue organoids from primary human ovarian surface epithelium (hOSE) cells. It details the isolation, expansion, cryopreservation, and organoid derivation processes, along with immunofluorescence and quantitative analysis.

Key Study Components

Area of Science

• Neuroscience
• Cell Biology
• Reproductive Health

Background

• Understanding ovarian function in humans is crucial for female reproductive health.
• 3D tissue culture protocols have advanced, allowing for the creation of artificial ovaries.
• Organoids provide a platform for studying ovarian biology and diseases.
• Challenges include donor variability and the need for non-pathological samples.

Purpose of Study

• To study the role of the human ovarian surface epithelium in tissue regeneration.
• To develop clinical protocols for ovarian function understanding.
• To address fundamental mechanistic questions about ovarian health.

Methods Used

• Isolation of hOSE cells from human ovaries.
• Cryopreservation and thawing of hOSE cells.
• Culture of hOSE cells in 2D and 3D environments.
• Immunofluorescence and quantitative analysis of organoids.

Main Results

• Primary hOSE cells exhibited cobblestone morphology up to passage three.
• 3D organoids from freshly isolated cells grew larger than those from 2D expanded cells.
• Various morphologies were observed in 3D organoids, indicating diverse growth patterns.
• Results highlight the potential of organoids for studying ovarian function.

Conclusions

• The OSC Organal protocol provides a valuable platform for ovarian research.
• Non-pathological samples enhance the applicability of findings to clinical settings.
• Further studies are needed to understand the regenerative mechanisms of the ovaries.
