ovided by experts should be tailored according to hospital capacity and different levels of the pandemic.Cell sorting can be used to purify cell populations for cell type-specific molecular probing. Fluorescence-activated cell sorting (FACS) coupled with high-throughput sequencing affords molecular signature identification for specific cell types. FACS has many challenges that limit comprehensive cell purification from the brain, leading to incomplete molecular characterization. Here, we present the intranuclear immunostaining-based FACS protocol with several modified steps, which allows optimized nuclei/cell sorting from mouse or human embryonic cortical tissue for distinct downstream molecular investigation of basal intermediate progenitors.Here, we describe a protocol to simultaneously record and label single cortical neurons in vivo under local application of a chemical such as a receptor agonist. This protocol provides a useful tool to investigate how the chemical of interest affects the processing of sensory information by cortical neurons. The juxtacellular labeling allows identification of the cell type and morphology of the recorded neurons. We draw examples to show pharmacological modulations in encoding of vibrotactile stimuli in the mouse primary somatosensory cortex. For complete details on the use and execution of this protocol, please refer to Kheradpezhouh et al. (2020).Renal progenitor cells induced from pluripotent stem cells have attracted attention as a cell source for organ regeneration. Here, we report an in vivo protocol for the regeneration of urine-producing nephrons, i.e., neo-nephrons, in mice. We outline steps to transplant exogenous renal progenitor cells into the nephrogenic zone of transgenic mice and subsequently analyze these neo-nephrons. For complete details on the use and execution of this protocol, please refer to Fujimoto et al. (2020).Hit-to-lead (H2L) optimization is crucial for drug design, which has become an increasing concern in medicinal chemistry. A virtual screening strategy of auto in silico ligand directing evolution (AILDE) has been developed to yield promising lead compounds rapidly and efficiently. The protocol includes instructions for fragment compound library construction, conformational sampling by molecular dynamics simulation, ligand modification by fragment growing, as well as the binding free energy prediction. For complete details on the use and execution of this protocol, please refer to Wu et al. (2020).The examination of circulating pro-vascular progenitor cell frequency and function is integral in understanding aberrant blood vessel homeostasis in individuals with cardiometabolic disease. Here, we outline the characterization of progenitor cell subsets from peripheral blood using high aldehyde dehydrogenase (ALDH) activity, an intracellular detoxification enzyme previously associated with pro-vascular progenitor cell status. Immunology agonist Using this protocol, cells can be examined by flow cytometry for ALDH activity and lineage restricted cell surface markers simultaneously. For complete details on the use and execution of this protocol, please refer to Terenzi et al. (2019) and Hess et al. (2019, 2020).In vivo cell migration is influenced by soluble factors as well as stiffness. Current in vitro strategies mostly account for one of these two factors to study cell migration. To understand the combinatorial effect of stiffness and chemokines on cell behavior, we have developed a microfluidic model to study stiffness-dependent chemotaxis of mesenchymal stem cells (hMSCs). A detailed description of our methodology will help researchers develop microfluidic models that combine these two factors influencing cell behavior. For complete details on the use and execution of this protocol, please refer to Saxena et al. (2018).To date, phase separation studies have largely been limited to in vitro assays using non-native conditions and aggregation-prone recombinant proteins that are often difficult to purify. This protocol describes the determination of relative protein concentration thresholds for phase separation through fluorescent imaging of GFP-tagged proteins in cells. The commercial availability of various plasmids and antibodies, as well as advances in gene editing, allow this procedure to be modified for the study of various phase-separating proteins in their relevant contexts. For complete details on the use and execution of this protocol, please refer to Lee et al. (2020).We present a detailed protocol for gene editing in adipocytes using the CRISPR-Cas technology. This protocol describes sgRNA design, preparation of lentiCRISPR-sgRNA vectors, functional validation of sgRNAs, preparation of lentiviruses, and lentiviruses transduction in adipocytes. Moreover, an optimized method of gene editing using the lentiCRISPRv2 vector expressing two sgRNAs targeting two different genes has also been described. For complete details on the use and execution of this protocol, please refer to Qiu et al. (2020).Confocal, multiphoton, or other advanced microscopy techniques produce high-quality datasets of calcium activity in live tissue. However, researchers without access to such expensive equipment can still produce meaningful observations from single-photon datasets. Here, we describe a protocol to extract meaningful features of both somatic neuronal and membranous astrocytic calcium dynamics obtained from charge-coupled device (CCD)-based camera setups, typical of electrophysiology rigs and highly relevant for investigating neuronal and astrocytic involvement in brain circuitry. For complete details on the use and execution of this protocol, please refer to Asrican et al. (2020).Social cooperation in rodents was recently validated in rats, and we recently successfully applied a modified automated analysis to mice. Here, we describe a detailed procedure for using this paradigm in mice that relies on reward-based mutual communication that is automatically detected by a software algorithm embedded in the custom-made equipment. We also describe exemplary results of analyses in mice as a guide to broader neuroscience research applications employing transgenic knockout mice modeling neuropsychiatric disorders and mice of various ages. For complete details on the use and execution of this protocol, please refer to Han et al. (2020).
