Bovine in vitro embryo production (IVP) has been around for about three decades. Over the years, it has gained a reputation as one of the most applicable of the high-tech bovine assisted reproduction techniques. It is well known that its ups and downs are basically driven by economic imperatives depending on the agricultural system in which it is used. In parallel, there has always been a stron...

Fibroblasts are predominant components of mammary stromal cells and play crucial roles in the development and involution of bovine mammary gland; however, whether these cells contribute to mastitis has not been demonstrated. Thus, we have undertaken biological and molecular characterization of inflammation-associated fibroblasts (INFs) extracted from bovine mammary glands with clinical mastitis...
