Molecular signaling of cardiac autonomic innervation is an unresolved issue. Here, we show that glial cell line-derived neurotrophic factor (GDNF) promotes cardiac sympathetic innervation in vitro and in vivo. In vitro, ventricular myocytes (VMs) and sympathetic neurons (SNs) isolated from neonatal rat ventricles and superior cervical ganglia were cultured at a close distance. Then, morphologic...

Ice recrystallization is the main contributor to cell damage and death during the cryopreservation of cells and tissues. Over the past five years, many small carbohydrate-based molecules were identified as ice recrystallization inhibitors and several were shown to reduce cryoinjury during the cryopreservation of red blood cells (RBCs) and hematopoietic stems cells (HSCs). Unfortunately, clear s...

BACKGROUND Chilling injury occurs when the cell membrane undergoes a transition from the liquid state to the gel state. Human oocytes and single-cell zygotes are of similar shape and size but the post-thawing survival rate of oocytes is poorer. We set out to investigate the possible difference in membrane lipid phase transition (LPT) temperature between the two cell types. METHODS The LPT tem...

This data article contains complementary figures related to the research article entitled, " A dual epimorphic and compensatory mode of heart regeneration" ([10], http://dx.doi.org/10.1016/j.ydbio.2014.12.002), which presents a spatial and temporal characterization of cardiomyocyte proliferation and dedifferentiation after cryoinjury-induced myocardial infarction. This study demonstrated that m...

Success in cryopreserving stallion semen has been very variable. Several different freezing regimes have been published. However, because extenders and procedures used in each regime have differed, direct comparison of these techniques has been very difficult, and controlled studies comparing different techniques have not been reported. A number of different factors affect sperm cryosurvival. I...

Oil palm (Elaeis guineensis) is the highest oil-yielding commercially grown perennial tree. germplasm conservation and in vitro clonal propagation strengthened world’s efforts to ensure future food security. Cryopreservation provides long-term storage for germplasm. The of plant material at cryogenic temperatures (−196 °C) following dehydration causes cryoinjury. cryotolerance mechanism has rar...

It is universally recognized that cryopreservation impairs sperm quality. In order to improve postthawing sperm survival and motility, media of different composition and different protocols have been proposed. However, no clear evidence is available to understand which are the most efficient protocol and medium for sperm cryopreservation. The present study evaluates the efficiency of two differ...

The adult human heart possesses a limited regenerative potential following an ischemic event, and undergoes a number of pathological changes in response to injury. Although cardiac regeneration has been documented in zebrafish and neonatal mouse hearts, it is currently unknown whether the immature human heart is capable of undergoing complete regeneration. Combined progress in pluripotent stem ...

Cold lesion injury applied to mouse brain and infusion of hyperosmolar L(+) arabinose solution into rat carotid artery were used as extravascular and intravascular insults, respectively, leading to blood-brain barrier (BBB) disruption. To study the cellular mechanisms of the BBB opening, heterologous (bovine) and homologous (mouse and rat) albumin-gold complexes were used as a macromolecular tr...

This study examined transgenic mice whose expression of a β-galactosidase (lacZ) reporter is driven by a GATA6 gene enhancer. Previous investigations established that transcription of the transgene was associated with precardiac mesoderm and primary heart tube myocardium, which decreased progressively, so that its expression was no longer observed within ventricular myocardium by midgestation. ...
