We provide a detailed description of a protocol for flow cytometric analysis of surface antigens and/or intracellular antigens in neural cell types. Critical aspects of experimental planning, step-by-step methodological procedures, and fundamental principles of flow cytometry are explained in order to enable neurobiologists to exploit this powerful technology.

Intra-articular injection of murine MSC for the treatment of inflammation and tissue degradation in Antigen-induced Arthritis.

Here, we present a protocol to induce inflammatory arthritis in vivo using antigen response, termed Antigen-induced Arthritis (AIA), an effective tool for research into Rheumatoid Arthritis (RA) research. Additionally we demonstrate the therapeutic effects of infusion of MSC to reduce inflammation, cartilage degradation and expression of TNFα.

The determination of the solution structure of a protein by small angle X-ray scattering (SAXS) requires monodisperse samples. Here, we present two possibilities to ensure minimal delays between sample preparation and data acquisition: online size-exclusion chromatography (SEC) and online ion-exchange chromatography (IEC).

Corneal Epithelial Abrasion with Ocular Burr As a Model for Cornea Wound Healing

Solja Kalha¹, Alison Kuony¹, Frederic Michon^1,2

¹Helsinki Institute of Life Science, Institute of Biotechnology, University of Helsinki, ²School of Medicine and Institute for Science and Technology in Medicine, Keele University

This protocol describes a method to inflict an abrasion to the ocular surface of the mouse, and to follow the wound healing process thereafter. The protocol takes advantage of an ocular burr to partially remove the surface epithelium of the eye in anaesthetized mice.

Medicine

Use of a Percutaneous Ventricular Assist Device/Left Atrium to Femoral Artery Bypass System for Cardiogenic Shock

Swethika Sundaravel¹, Poonam Velagapudi¹, Mamas Mamas², Sandeep Nathan³, Alexander Truesdell⁴

¹University of Nebraska Medical Center, ²Keele Cardiovascular Research Group, Keele University, ³University of Chicago Medicine, ⁴Virginia Heart/Inova Heart and Vascular Institute

The following article describes the stepwise procedure for placement of a device (e.g., Tandemheart) in cardiogenic shock (CS) that is a percutaneous left ventricular assist device (pLVAD) and a left atrial to femoral artery bypass (LAFAB) system that bypasses and supports the left ventricle (LV) in CS.

Despite the advancements in multiplex immunohistochemistry and multispectral imaging, characterizing the density and clustering of major immune cells simultaneously in the endometrium remains a challenge. This paper describes a detailed multiplex staining protocol and imaging for the simultaneous localization of four immune cell types in the endometrium.
