简介：
Overview
This article presents a technique for explant cell culture derived from the leptomeninges of postmortem human brain. The protocol allows for the derivation of fibronectin-positive meningeal fibroblasts within 6-8 weeks, facilitating the study of cell lines from patients with Parkinson's disease.

What is the significance of using postmortem brain tissue?
Postmortem brain tissue allows researchers to study cells from patients with confirmed neurological conditions, providing valuable insights into disease mechanisms.
How long does the fibroblast derivation process take?
The process typically takes 6-8 weeks to derive fibronectin-positive meningeal fibroblasts.
What applications can these fibroblasts be used for?
These fibroblasts can be used in various cell-based assays to study cellular responses and disease mechanisms.
What precautions are taken during the culture process?
All materials entering the tissue culture hood must be sterilized with 70% ethanol to prevent contamination.
Can these cells be cryopreserved?
Yes, approximately 20-30 million cells can be cryopreserved for future use.
What is the role of fibronectin in this study?
Fibronectin is a marker used to identify and characterize the derived meningeal fibroblasts.
