Dorper sheep are celebrated for their fast maturation and superior meat quality, with some shedding their wool each spring. Wool shedding occurs naturally due to the hair follicle (HF) cycle, but its regulatory mechanisms remain unclear and need further investigation. Results In this study, sheddin...
Finally, the study provides a theoretical reference for molecular breeding of sheep breeds as well as for the investigation of the origin and evolution of animal hair.Xue PuShengchao MaBingru ZhaoSen TangQingwei LuWenna LiuYaqian WangYunlin Cen...
The HF development directly affects the production and quality of sheep wool. In sheep breeding, the quality and yield of sheep wool can be improved by studying the genes that regulate the development of HF. The structure of the HF in mammals is complex. HF development occurs during fetal ski...
In our study, we found by q RT-PCR that miR-148 b was signi ficantly upregulated in sheep wool follicle bulbs in anagen phase compared with the telogen phase of the hair follicle cycle. Overexpression of miR-148 b promoted proliferation of both HHDPC and HHGMC. By using the TOPFlash ...

(postnatal day 7, P7), and postnatal hair cycle stages (P30) [3,4]. The number of dermal papilla cells and the size of hair placode are associated with the diameter, crimp, and density of wool fibres [3], which are of high economic value in sheep industry. In addition, the normal...
In the present study, Morada Nova sheep from two Brazilian states: Ceará (140 animals) and São Paulo (112 animals) were genotyped for a SNP associated with litter size, which is almost only found in Brazilian locally adapted sheep breeds (FecGE). The total observed frequency ofFecGEwas ...

miRNAs and target genes related to hair follicular development were found, which provided a theoretical basis for molecular breeding for the culture of fine-wool sheep.doi:10.1186/s12864-022-08954-2He, JunminHuang, XixiaZhao, BingruLiu, Guifen...
Cashmere quality is affected by genetic, breeding management and environmental factors [28,29,30,31]. With increase in age, the fleece or cashmere yield of sheep and goats showed a trend of increase and then decrease [32,33]. The cashmere diameter of Inner Mongolia and Liaoning cashmere ...
