Adult Stem Cell Research in Light of the Bovine Mammary Gland Regenerative Medicine

Abstract

Abstract: The bovine mammary gland has vital importance in the dairy sector, as it is considered a source of basic dairy product, milk. Mammary gland affections are widespread, which affect the dairy industry economically and pose a potential public health hazard. Current therapeutic options are ineffective in controlling the infection and regenerating the gland effectively. Antimicrobials commonly used against mastitis make their way into the milk . In order to find a solution to these problems, advanced therapeutic options, like the one for stem cells, are considered. Mammary gland stem cells (MaSCs) are considered to maintain tissue homeostasis. The characterization of these cells and their derived lineages (progenitor cells and mammary epithelial cells) may potentially provide the physiological status or production potential of the gland. However, current isolation methods are cumbersome and fall short to isolate a pure line of cattle MaSCs from progenitors or other differentiated epithelial cells. An alternative to the therapeutic application of MaSCs is the mesenchymal stem cell (MSC). These cells can potentially control microbial infection, show anti-inflammatory and other pro-healing effects, and furthermore enhance mammary epithelial cell secretory potential to ensure tissue regeneration. The current review focuses on MaSCs and MSCs properties in light of the bovine mammary gland regeneration.
