    Notochord Injury Assays that Stimulate Transcriptional Responses in Zebrafish Larvae
    [Abstract] Zebrafish have become an increasingly important model organism in the field of wound healing and regenerative medicine, due to their high regenerative capacity coupled with high-resolution imaging in living animals. In a recent study, we described multiple physical and chemical methods to induce notochord injury that led to highly specific ...
    Generation of BMEC Lines and in vitro BMEC-HSPC Co-culture Assays
    Authors:  Peipei Guo and Shahin Rafii, date: 11/05/2018, view: 202, Q&A: 0
    [Abstract] Endothelial cells (ECs) sustain the self-renewal and regeneration of adult hematopoietic stem and progenitor cells (HSPCs) via deployment of EC-derived paracrine factors, termed as angiocrine factors. Generation of durable ex vivo vascular niche that maintains EC identity and preserves the angiocrine profile of organ of origin offers ...
    Detection of Cell Death in Planarians
    Authors:  Nídia de Sousa and Teresa Adell, date: 10/05/2018, view: 475, Q&A: 0
    [Abstract] Planarians are freshwater flatworms, well known for their ability to regenerate a complete organism from any piece of their body. Furthermore, planarians are constantly growing and degrowing throughout their lives, maintaining a functional and proportioned body. These properties rely on the presence of a population of adult stem cells and on the ...
    Human Endothelial Cell Spheroid-based Sprouting Angiogenesis Assay in Collagen
    Authors:  Fabian Tetzlaff and Andreas Fischer, date: 09/05/2018, view: 793, Q&A: 0
    [Abstract] Angiogenesis, the formation of new blood vessels from pre-existing ones plays an important role during organ development, regeneration and tumor progression. The spheroid-based sprouting assay is a well-established and robust method to study the influence of genetic alterations or pharmacological compounds on capillary-like tube formation of ...
    Pollen Germination and Pollen Tube Growth of Arabidopsis thaliana: In vitro and Semi in vivo Methods
    Authors:  Hugh Dickinson, Josefina Rodriguez-Enriquez and Robert Grant-Downton , date: 08/20/2018, view: 889, Q&A: 0
    [Abstract] Studies of pollen germination and post-germination development are not only essential for understanding plant reproduction but also are an excellent model system for tip-based growth. Here we describe easy, reproducible methods for germination and growth of pollen from the model plant Arabidopsis thaliana in artificial conditions. Our ...
    Isolation of LYVE-1+ Endothelial Cells from Mouse Embryos
    Author:  Patrick Crosswhite, date: 08/05/2018, view: 488, Q&A: 0
    [Abstract] Lymphatic vessel endothelial hyaluronan receptor 1, or LYVE-1, is a type 1 integral membrane glycoprotein expressed by lymphatic endothelial cells (LECs). LYVE-1 is commonly used as a biological marker to visually distinguish developing lymphatic vessels from blood endothelial cells (arteries or veins). As our understanding of lymphatic biology is ...
    Muscle Function Assessment Using a Drosophila Larvae Crawling Assay
    Authors:  Yanina Post and Achim Paululat, date: 07/20/2018, view: 650, Q&A: 0
    [Abstract] Here we describe a simple method to measure larval muscle contraction and locomotion behavior. The method enables the user to acquire data, without the necessity of using expensive equipment (Rotstein et al., 2018). To measure contraction and locomotion behaviour, single larvae are positioned at the center of a humidified Petri dish. ...
    Visualization of RNA at the Single Cell Level by Fluorescent in situ Hybridization Coupled to Flow Cytometry
    Authors:  Alice Coillard and Elodie Segura, date: 06/20/2018, view: 1208, Q&A: 0
    [Abstract] The protocol described here has been developed to detect RNA at the single cell level. Fluorescent probes hybridize to target RNAs and are detected by flow cytometry after multiple amplification steps. Different types of RNA can be detected such as mRNA, long noncoding RNA, viral RNA or telomere RNA and up to 4 different target probes can be used ...
    In vitro Osteoclastogenesis Assays Using Primary Mouse Bone Marrow Cells
    Authors:  Xueqian Zhuang and Guohong Hu, date: 06/05/2018, view: 1152, Q&A: 1
    [Abstract] Osteoclasts are a group of bone-absorbing cells to degenerate bone matrix and play pivotal roles in bone growth and homeostasis. The unbalanced induction of osteoclast differentiation (osteoclastogenesis) in pathological conditions, such as osteoporosis, arthritis and skeleton metastasis of cancer, causes great pain, bone fracture, hypercalcemia ...
    A Microfluidic Device for Massively Parallel, Whole-lifespan Imaging of Single Fission Yeast Cells
    Authors:  Stephen K Jones Jr, Eric C Spivey, James R Rybarski and Ilya J Finkelstein, date: 04/05/2018, view: 1555, Q&A: 0
    [Abstract] Whole-lifespan single-cell analysis has greatly increased our understanding of fundamental cellular processes such as cellular aging. To observe individual cells across their entire lifespan, all progeny must be removed from the growth medium, typically via manual microdissection. However, manual microdissection is laborious, low-throughput, and ...
