Harvest and Primary Culture of Leptomeningeal Lymphatic Endothelial Cells

2.3K
Leptomeningeal lymphatic endothelial cells (LLECs), a recently identified intracranial cell type, have poorly understood functions. This study presents a reproducible protocol for harvesting LLECs from mice and establishing in vitro primary cultures. This protocol is designed to enable researchers to delve into the cellular functions and potential clinical implications of...

Induction of Leptomeningeal Cells Modification Via Intracisternal Injection

8.9K
We describe an intracisternal injection that employs a needle bent at the tip that can be stabilized to the skull, thus eliminating the risk of damage to the underlying parenchyma. The approach can be used for genetic fate mapping and manipulations of leptomeningeal cells and for tracking cerebrospinal fluid...

Area of Science:

  • Neurology
  • Oncology
  • Cancer Research

Background:

  • Leptomeningeal metastasis (LM) is a frequent and severe neurologic complication of cancer.
  • Current treatments for LM aim to preserve function and improve quality of life, but cures are not yet available.

Purpose of the Study:

  • To highlight the need for further research into LM mechanisms for targeted therapies.
  • To emphasize the necessity of developing novel drug-based and radiation-based treatments for LM.
  • To advocate for the development of surrogate markers and appropriate clinical trial designs for LM.

Main Methods:

  • Review of current understanding and treatment strategies for leptomeningeal metastasis.
  • Discussion of the role of animal models in studying LM pathophysiology and treatment efficacy.
  • Emphasis on the importance of randomized clinical trials for evaluating new LM interventions.

Main Results:

  • LM presents with diverse clinical symptoms and is associated with a poor prognosis in advanced cancer.
  • Early diagnosis and intervention are crucial for managing LM and improving patient outcomes.
  • Prevention or delay of neurologic progression is a key endpoint for clinical trials in LM.

Conclusions:

  • Further research into LM pathogenesis is essential for identifying new therapeutic targets.
  • Development of effective drug-based and radiation-based treatments is urgently needed.
  • Early recognition and diagnosis of LM by physicians can lead to improved quality of life and potentially survival for patients.
