Here, a protocol is presented to assess mouse meningeal lymphatic vessels (MLVs), which play an important role in multiple neurologic diseases. The goal of this protocol is to provide an integrated method that enables both functional evaluation of tracer drainage and detailed morphological characterization of the dorsal MLVs network.

Generation of induced pluripotent stem cells provides fascinating prospects for the derivation of autologous transplants. However, progression through a pluripotent state and laborious re-differentiation still hinders clinical translation. Here we describe the derivation of adult human fibroblasts and their direct conversion into induced neural progenitor cells and the subsequent differentiation into neural lineages.

2026
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

This video demonstrates a technique for isolating induced neural progenitor cells (iNPCs) derived from adult human fibroblasts. It outlines the steps involved in isolating the iNPC colonies and culturing them in laminin-coated multi-well plate wells in the presence of suitable culture media that facilitate the continued proliferation and expansion of the iNPC population.
FAQs
Enrichment depends on conditions that favor fibroblast attachment, survival, and proliferation after meningeal tissue is processed. Handling and continued culture can reduce the representation of nonfibroblast populations, producing a more experimentally accessible fibroblast population. This selection is important because the resulting culture better supports focused analysis of meningeal extracellular matrix production and cell signaling.
Meningeal fibroblasts provide a cellular model for examining how the connective tissue surrounding the nervous system produces extracellular matrix. Studying this activity helps researchers investigate structural regulation at the brain’s protective interfaces and assess how matrix-related behavior changes under experimental conditions. The cultures therefore connect cellular mechanisms with tissue organization and repair-related questions in neuroscience.
These cultures can be used to examine signaling between meningeal fibroblasts and neural or immune cells. Such interactions are relevant to neuroinflammation and to regulation of the protective interfaces around the brain and spinal cord. Because the fibroblasts can be studied outside intact tissue, experiments can focus on how their signals or matrix-related activities influence neighboring cell responses.
The outcome depends on several linked stages: accurate meningeal dissection, effective tissue dissociation, and culture conditions that support attachment, survival, and proliferation. Handling also influences which nonfibroblast populations remain represented. Together, these factors affect the composition and expansion of the resulting culture, which in turn determines how consistently it can model meningeal cellular behavior.
A typical workflow begins with dissecting meningeal tissue, followed by dissociation into individual cells. The cells are then placed under controlled culture conditions that permit attachment, survival, and proliferation. Continued handling and culture selection reduce nonfibroblast populations while the fibroblasts expand. This sequence produces cells suitable for experiments on meningeal extracellular matrix, signaling, and cellular interactions.
Researchers can use derived meningeal fibroblasts when they need an accessible system for studying neuroinflammation, barrier regulation, tissue repair, or disease-related changes at the brain’s protective interfaces. The cultures allow cellular processes to be examined under controlled conditions rather than only within intact meningeal tissue, making them useful for investigating fibroblast behavior and communication with neural or immune cells.
Experiments with these cultures can provide information about extracellular matrix production, fibroblast signaling, and interactions with neural or immune cells. They can also help reveal changes associated with tissue repair, barrier regulation, neuroinflammation, or disease-related conditions at the meninges. These outcomes connect cellular observations to the broader function of the nervous system’s protective connective tissue interfaces.
