Role of chemokines in regulating luteal and uterine functions in pregnant cows
Ryosuke SAKUMOTO
Volume 70 Issue 3 Pages 145-151
Cover Story:
Chemokines are known to regulate various reproductive functions, such as regulation of corpus luteum (CL) and uterine functions in cows. However, the role of chemokines in pregnancy has not yet been fully elucidated. Sakumoto summarized and reviewed the literature on chemokine (-receptor) expression and its physiological roles in the bovine CL and uterus during pregnancy. This review will help understand the mechanisms of chemokine-mediated interactions among the CL, uterus, immune cells, and conceptus during pregnancy in cows.

Efficient derivation of embryonic stem cells and primordial germ cell-like cells in cattle
Atsushi SHIRASAWA, Masafumi HAYASHI, Mayumi SHONO, Atsushi IDETA, Takashi YOSHINO, Katsuhiko HAYASHI
Volume 70 Issue 2 Pages 82-95
Cover Story:
The process of inducing the germ cell lineage from pluripotent stem cells, referred to as in vitro gametogenesis, aids in comprehending the mechanisms involved in germ cell differentiation and offers an alternative source of gametes for reproduction. Shirasawa et al. have developed a novel method for robust induction of primordial germ cell-like cells (PGCLCs) from newly established bovine embryonic stem (bES) cells. After a 24-hour culture with bone morphogenetic protein 4 (BMP4), followed by a three-dimensional culture with BMP4 and chemicals modulating WNT signaling, bES cells exhibited positive expression for a set of primordial germ cell (PGC) markers, including PRDM1/BLIMP1, TFAP2C, and SOX17. These outcomes are anticipated to have practical implications for the development of stem cell-based reproductive technologies in cattle.

Review
Improvements in in vitro spermatogenesis: oxygen concentration, antioxidants, tissue-form design, and space control
Takehiko OGAWA, Takafumi MATSUMURA, Tatsuma YAO, Hiroshi KIMURA, Kiyoshi HASHIMOTO, Yu ISHIKAWA-YAMAUCHI, Takuya SATO
Volume 70 Issue 1 Pages 1-9
Cover Story:
For the past century, achieving in vitro spermatogenesis has remained a difficult challenge for researchers. In 2011, Ogawa et al. successfully demonstrated in vitro spermatogenesis in mice using an organ culture method. However, extending this method to other species posed challenges for over a decade. In 2023, Ogawa’s team achieved in vitro spermatogenesis in rats by incorporating several critical modifications to enhance their original technique. This review presents a detailed analysis by Ogawa et al. comparing their method with natural in vivo conditions and other synthetic alternatives. They systematically explore the merits, limitations, and inherent constraints of the organ culture approach, delving into the specifics of medium composition, the principles of the gas-liquid interphase method, use of microfluidic devices, and innovation of the PDMS-ceiling method. Highlighting the challenges faced, including regulating oxygen concentration, managing tissue formation, and regulating culture space-control. The insights and novel concepts shared in this review are particularly valuable for those involved in culture or related disciplines, providing innovative content, and encouraging further exploration in this field.
