Schwann cells; amputation; axons; bone marrow; immunohistochemistry; innervation; mice; nerve regeneration; nerve tissue; peripheral nerves; regrowth; substance P; tyrosine 3-monooxygenase
Abstract:
... Mice are intrinsically capable of regenerating the tips of their digits after amputation. Mouse digit tip regeneration is reported to be a peripheral nerve-dependent event. However, it is presently unknown what types of nerves and Schwann cells innervate the digit tip, and to what extent these cells regenerate in association with the regenerative response. Given the necessity of peripheral nerves ...

Abstract:
... Studying microRNA networks during heart development is essential to obtain a better understanding of developmental defects and diseases associated with the heart and to identify novel opportunities for therapeutics. Here we highlight the advantages of chicken embryos as a vertebrate model for studying intermediate processes of heart development. Avians develop a four-chambered heart closely resemb ...

Subject:
abnormal development; death; embryogenesis; endothelium; germ cells; heart; knockout mutants; mice; phenotype; progeny; transcription factors; viability
Abstract:
... MEF2C is a member of the highly conserved MEF2 family of transcription factors and is a key regulator of cardiovascular development. In mice, Mef2c is expressed in the developing heart and vasculature, including the endothelium. Loss of Mef2c function in germline knockout mice leads to early embryonic demise and profound developmental abnormalities in the cardiovascular system. Previous attempts t ...

Abstract:
... We recently demonstrated the requirement of two-pore channel type 2 (TPC2)-mediated Ca2+ release during slow muscle cell differentiation and motor circuit maturation in intact zebrafish embryos. However, the upstream trigger(s) of TPC2/Ca2+ signaling during these developmental processes remains unclear. Nicotinic acid adenine dinucleotide phosphate (NAADP) is a potent Ca2+ mobilizing messenger, wh ...

Abstract:
... Epigenetic alterations in the germline can be triggered by a number of different environmental factors from diet to toxicants. These environmentally induced germline changes can promote the epigenetic transgenerational inheritance of disease and phenotypic variation. In previous studies, the pesticide DDT was shown to promote the transgenerational inheritance of sperm differential DNA methylation ...

Abstract:
... The enteric nervous system is thought to originate solely from the neural crest. Transgenic lineage tracing revealed a novel population of clonal pancreatic duodenal homeobox-1 (Pdx1)-Cre lineage progenitor cells in the tunica muscularis of the gut that produced pancreatic descendants as well as neurons upon differentiation in vitro. Additionally, an in vivo subpopulation of endoderm lineage enter ...

Abstract:
... The mammary gland (MG) is a unique organ responsible for milk synthesis, secretion, and involution to prepare the gland for subsequent lactation. The mammary epithelial cells (MECs), which are the milk synthesizing units of the MG, proliferate, differentiate, undergo apoptosis and regenerate following a cyclic pathway of lactation – involution – lactation, fine-tuning these molecular events throug ...

Abstract:
... Regeneration, the ability to restore body parts after an injury or an amputation, is a widespread but highly variable and complex phenomenon in animals. While having fascinated scientists for centuries, fundamental questions about the cellular basis of animal regeneration as well as its evolutionary history remain largely unanswered. Here, we present a study of regeneration of the marine annelid P ...

Abstract:
... The CRISPR/Cas9 system is a rapid, simple, and often extremely efficient gene editing method. This method has been used in a variety of organisms and cell types over the past several years. However, using this technology for generating gene-edited animals involves a number of obstacles. One such obstacle is mosaicism, which is common in founder animals. This is especially the case when the CRISPR/ ...

Studies on the mechanisms underlying the therapeutic effects of stem cells on skin wound healing will be needed. Hence, in the present study, we explored the role of Caveolin-1 in epidermal stem cells (EpiSCs) in the modulation of wound healing. We first isolated EpiSCs from mo ...

Abstract:
... During development diverse transcription factor inputs are integrated by cis-regulatory modules (CRMs) to yield cell-specific gene expression. Defining how CRMs recruit the appropriate combinations of factors to either activate or repress gene expression remains a challenge. In this study, we compare and contrast the ability of two CRMs within the Drosophila embryo to recruit functional Hox transc ...

Abstract:
... β-TrCP is the substrate recognition subunit of an SCF-type ubiquitin ligase. We recently showed that deletion of the genes for both β-TrCP1 and β-TrCP2 paralogs in germ cells of male mice resulted in accumulation of the transcription factor DMRT1 and spermatogenic failure, whereas systemic β-TrCP1 knockout combined with β-TrCP2 knockdown had previously been shown to lead to disruption of testicula ...
