“…However, we previously reported on concurrent CAV and infectious bronchitis virus (IBV) in diseased chicks in Hiroshima prefecture in 2017. Severe hematopoietic and lymphocytic depletion with abnormally large cells containing intranuclear inclusion bodies were observed in bone marrow, spleen, and liver due to CAV infection, whereas renal tubular necrosis was also recorded in diseased chicks caused by IBV infection [6]. The CAV isolated from the outbreak caused 100% anemia and 70% mortality in one-day-old chicks.…”

“…However, monitoring CAV infection has not been a priority in poultry disease control. In recent years, several studies on CAV infection and its disease, which affected the chicken production industry in Japan, were reported [1,6]. Del Valle et al [1] reported chickens showing clinical signs of diseases caused by CAV infection in distinct farms in eastern Japan (Ibaraki, Fukushima, and Chiba prefectures) from 2013 to 2016.…”

“…Later, one outbreak of CAV infection was recorded in a broiler chicken farm in Hiroshima prefecture in 2019, which caused uncommon mortality in young chickens. The CAV isolate was classified as causing high mortality in specific-pathogen-free chickens [6]. This study describes two new cases of CAV infection outbreaks and the disease caused by the infection in Japan.…”

“…It was reported that the lack of a CAV vaccination program in parent flocks might result in CAVrelated disease in their broiler chicken farms in Japan recently [6]. CAV is characterized as a single serotype.…”

In this study, a total of nine chicken samples obtained from two broiler flocks in Oita and Tottori prefectures in 2020 were examined for Chicken anemia virus (CAV) infection. The samples were collected from clinically suspected flocks and diseased chickens. The CAV genome was detected in all nine samples tested by real-time PCR. Phylogenetic analyses and sequence comparisons of the full-length VP1 gene sequences indicated that all the Japanese CAV strains obtained in this study formed a similar cluster of genotype III and shared high nucleotide (99.62%-100%) identity. The current Japanese CAV strains were closely related to Chinese CAV strains but not related to vaccine strains. One positive selection site of VP1 was detected among the Japanese CAV strains.

“…As a precursor of immune cells, hematopoietic stem cells (HSC) play an indispensable role in the immune response against the main avian diseases ( Cui et al, 2009 ; Gurung et al, 2017 ; Hosokawa et al, 2020 ). HSC reside in a unique bone marrow environment, where they interact with other cells and molecules to create a bone marrow niche ( Zhang P. et al, 2019 ).…”

Three-dimensional (3D) cell culture is attracting increasing attention today because it can mimic tissue environments and provide more realistic results than do conventional cell cultures. On the other hand, very little attention has been given to using 3D cell cultures in the field of avian cell biology. Although mimicking the bone marrow niche is a classic challenge of mammalian stem cell research, experiments have never been conducted in poultry on preparing in vitro the bone marrow niche. It is well known, however, that all diseases cause immunosuppression and target immune cells and their development. Hematopoietic stem cells (HSC) reside in the bone marrow and constitute a source for immune cells of lymphoid and myeloid origins. Disease prevention and control in poultry are facing new challenges, such as greater use of alternative breeding systems and expanding production of eggs and chicken meat in developing countries. Moreover, the COVID-19 pandemic will draw greater attention to the importance of disease management in poultry because poultry constitutes a rich source of zoonotic diseases. For these reasons, and because they will lead to a better understanding of disease pathogenesis, in vivo HSC niches for studying disease pathogenesis can be valuable tools for developing more effective disease prevention, diagnosis, and control. The main goal of this review is to summarize knowledge about avian hematopoietic cells, HSC niches, avian immunosuppressive diseases, and isolation of HSC, and the main part of the review is dedicated to using 3D cell cultures and their possible use for studying disease pathogenesis with practical examples. Therefore, this review can serve as a practical guide to support further preparation of 3D avian HSC niches to study the pathogenesis of avian diseases.
