Whole-cell Patch-clamp Recordings in Brain Slices
Abstract
Whole-cell patch-clamp recording is an electrophysiological technique that allows the study of the electrical properties of a substantial part of the neuron. In this configuration, the micropipette is in tight contact with the cell membrane, which prevents current leakage and thereby provides more accurate ionic current measurements than the previously used intracellular sharp electrode recording method. Classically, whole-cell recording can be performed on neurons in various types of preparations, including cell culture models, dissociated neurons, neurons in brain slices, and in intact anesthetized or awake animals. In summary, this technique has immensely contributed to the understanding of passive and active biophysical properties of excitable cells. A major advantage of this technique is that it provides information on how specific manipulations (e.g., pharmacological, experimenter-induced plasticity) may alter specific neuronal functions or channels in real-time. Additionally, significant opening of the plasma membrane allows the internal pipette solution to freely diffuse into the cytoplasm, providing means for introducing drugs, e.g., agonists or antagonists of specific intracellular proteins, and manipulating these targets without altering their functions in neighboring cells. This article will focus on whole-cell recording performed on neurons in brain slices, a preparation that has the advantage of recording neurons in relatively well preserved brain circuits, i.e., in a physiologically relevant context. In particular, when combined with appropriate pharmacology, this technique is a powerful tool allowing identification of specific neuroadaptations that occurred following any type of experiences, such as learning, exposure to drugs of abuse, and stress. In summary, whole-cell patch-clamp recordings in brain slices provide means to measure in ex vivo preparation long-lasting changes in neuronal functions that have developed in intact awake animals

Cell Labeling and Targeting with Superparamagnetic Iron Oxide Nanoparticles
Переглядів 4,9 тис.3 роки тому
Abstract Targeted delivery of cells and therapeutic agents would benefit a wide range of biomedical applications by concentrating the therapeutic effect at the target site while minimizing deleterious effects to off-target sites. Magnetic cell targeting is an efficient, safe, and straightforward delivery technique. Superparamagnetic iron oxide nanoparticles (SPION) are biodegradable, biocompati...
Isolating Stem Cells from Soft Musculoskeletal Tissues
Переглядів 7143 роки тому
Abstract Adult stem cells have long been discussed in regards to their application in regenerative medicine. Adult stem cells have generated a great deal of excitement for treating injured and diseased tissues due to their impressive capabilities to undergo multi-lineage cell differentiation and their selfrenewal ability. Most importantly, these qualities have made them advantageous for use in ...
Intravenous Injections in Neonatal Mice
Переглядів 4,2 тис.3 роки тому
Abstract Intravenous injection is a clinically applicable manner to deliver therapeutics. For adult rodents and larger animals, intravenous injections are technically feasible and routine. However, some mouse models can have early onset of disease with a rapid progression that makes administration of potential therapies difficult. The temporal (or facial) vein is just anterior to the ear bud in...

Abstract Micro-dissection of rat brain into various regions is extremely important for the study of different neurodegenerative diseases. This video demonstrates micro-dissection of four major brain regions include olfactory bulb, frontal cortex, striatum and hippocampus in fresh rat brain tissue. Useful tips for quick removal of respective regions to avoid RNA and protein degradation of the ti...
A Cancer Cell Spheroid Assay to Assess Invasion in a 3D Setting
Переглядів 3,7 тис.3 роки тому
Abstract The invasive nature of cancer cell lines is thought to correlate with their metastatic potential. Most traditional assays, however, do not examine these invasive features in a three-dimensional environment and the resulting data suffer from reduced biological applicability. Here an approach is presented to visualize the invasive ability of cell lines in a physiologically relevant setti...
The Sciatic Nerve Cuffing Model of Neuropathic Pain in Mice
Переглядів 3,2 тис.3 роки тому
Abstract Neuropathic pain arises as a consequence of a lesion or a disease affecting the somatosensory system. This syndrome results from maladaptive changes in injured sensory neurons and along the entire nociceptive pathway within the central nervous system. It is usually chronic and challenging to treat. In order to study neuropathic pain and its treatments, different models have been develo...
Transplantation of MACS Purified Photoreceptor Precursor Cells into the Adult Mouse Retina
Переглядів 2433 роки тому
Abstract Vision impairment and blindness due to the loss of the light-sensing cells of the retina, i.e. photoreceptors, represents the main reason for disability in industrialized countries. Replacement of degenerated photoreceptors by cell transplantation represents a possible treatment option in future clinical applications. Indeed, recent preclinical studies demonstrated that immature photor...
Systemic and Local Drug Delivery for Treating Diseases of the Central Nervous System
Переглядів 1613 роки тому
Abstract Thorough preclinical testing of central nervous system (CNS) therapeutics includes a consideration of routes of administration and agent biodistribution in assessing therapeutic efficacy. Between the two major classifications of administration, local vs. systemic, systemic delivery approaches are often preferred due to ease of administration. However, systemic delivery may result in su...
Advanced Patch-Clamp Analysis for Neuroscientist
Переглядів 1,4 тис.3 роки тому
Abstract The introduction of whole-cell, patch clamp recordings in vivo has allowed measuring the synaptic (excitatoryand inhibitory) inputs and the spike output from molecularly or anatomically identified neurons. Combining this technique with two-photon microscopy also allows to optically target such recordings to the different subtypes of inhibitory cells (e.g., soma- and dendrite targeting),...

Hold the tail when lifting at 1:15 can a rat support its weight with just the tail?
well explanatory
Even a mature individual like the one shown at 1:14 would not bathe in a water-tight bath, right? Chocolate in low concentrations is also poisonous to these individuals, even in minute quantities, right? And sterilized cucumbers and strawberries are equally dangerous, right?
Dear sir lots of peoples waiting for you great treatment 🙏 please help
Wow

How many uL would you think could be collected from a Syrian Golden Hamster during a terminal collection under ISO with this technique?
A nice video!

switching between SDS and OBS I've found can cause damage to cell structure and in cases of more delicate structures swapping once for a period of 5-10 minutes was sufficient
I want to work with u ..how can I approach?
