Abstract
Satellite cells are an important cellular model for studying muscle growth and development and mammalian locomotion-related molecular mechanisms. In this study, we investigated the effects of voltage, pulse duration, and DNA dosage on horse skeletal muscle satellite cells' electroporation transfection efficiency using the eukaryotic expression plasmid Td Tomato-C1 (5.5 kb) encoding the red fluorescent protein gene mainly based on fluorescence-positive cell rate and cell survival rate. By comparison of different voltages, pulse durations, and DNA doses, horse skeletal muscle satellite cells have nearly 80% transfection efficiency under the condition of voltage 120 V, DNA dosage 7 µg/ml, and pulse duration 30 ms. This optimized electroporation condition would facilitate the application of horse skeletal muscle satellite cells in genetic studies of muscle function and related diseases.

Abstract
BACKGROUND Proliferation of embryonic fibroblasts under the same cell culture conditions, hinny embryonic fibroblasts (HiEFs) was slower than horse embryonic fibroblast (HEFs), donkey embryonic fibroblasts (DEFs) and mule embryonic fibroblasts (MuEFs). The imprinted genes IGF2 and IGF2R are important for cell proliferation. Therefore, we investigated whether the slower proliferation of HiEFs is related to an aberrant gene expression of IGF2 or its receptors or genes influencing the expression of the IGF2 system. METHODS AND RESULTS Real-time polymerase chain reaction, immunofluorescence and cell starving experiment in HEFs, DEFs, MuEFs and HiEFs revealed that the slower proliferation of HiEF in vitro was related to its lower expression of IGF2R (P < 0.001). Moreover, quantification of allele-specific expression and bisulfate assay confirmed that in both MuEFs and HiEFs, IGF2R had normal maternal imprinting, implying that the imprint aberrant was not involved in the lower IGF2R expression in HiEFs. CONCLUSIONS The reduction of IGF2R expression in HiEFs is associated with its slower proliferation in vitro.

Abstract
During equine early gestation, trophectoderm forms chorion tissue, which is composed of two parts that one is covering allantoin, called allantochorion (AC) and another is covering yolk sac, which here we call vitelline-chorion (VC). Given that little is known about the equine trophoblast-derived chorion differentiation at an early stage, we first compared the transcriptome of AC and VC of day 30 equine conceptus based on RNA-sequencing. As a result, we found that compared to VC, there are 484 DEGs, including 305 up- and 179 down-regulated genes in AC. GO and KEGG analysis indicated that up-regulated genes in AC are mainly cell proliferation and cell adhesion-related genes, participating in allantois expansion and allantochorionic-placenta formation; dominant genes in VC are extracellular exosome and other cell adhesion-related genes implicated in direct and indirect conceptus-maternal communication. Additionally, as for the progenitor chorion tissue of equine chorionic gonadotropin secreting endometrium cup-the chorionic girdle (CG), which locates at the junction of the dilating AC and regressing VC, we revealed its unique gene expression pattern and the gene regulation during its further differentiation in vitro. Collectively, this study sheds light on the molecular events regarding the trophoblast differentiation and function at an early stage of the equine preimplantation conceptus.

Abstract
The hump attachment structure was morphologically examined in the two-humped camel (Camelus bactrianus). The cranial hump is fixed by the trapezius and rhomboid muscles in the thoracic region. The strong collagen sheet in the basement of the hump is attached to the segmented bellies of the trapezius muscle, and the thoracic rhomboid muscle and the nuchal-supraspinous ligament support the attachment function of the trapezius muscle. The basement sheet possesses the line structure of collagen fibers, which are fitted to the segmented bundles of the trapezius muscle, and we observed that the muscle cells of the trapezius muscle are intermingled with the collagen fibers around the attachment line structure. In contrast, the caudal hump is directly attached to the subcutaneous tissue in the superficial region of the lumbar longissimus and lumbar iliocostal muscles. These findings demonstrated that the caudal hump of the two-humped camel is consistent with the hump of the one-humped camel in the attachment structure.
