Project description:Orangutans are an endangered species whose natural habitats are restricted to the Southeast Asian islands of Borneo and Sumatra. For potential species conservation and functional genomics studies, we derived induced pluripotent stem cells (iPSCs) from cryopreserved skin fibroblasts obtained from captive orangutans. We report the gene expression profiles of iPSCs and skin fibroblasts derived from orangtuans.
Project description:Asian salamander Hynobiidae is commonly observed in the Far East Asia regions, including Korea, Japan, China, and the eastern region of Russia. In Korea, there are four Hynobiidae species known to be lived: Hynobius leechii, Hynobius quelpaertensis, Hynobius yangi, and recently reported Hynobius unisacculus. However, even H. leechii which is broadly colonized in Korea peninsula seems to have a new species candidate, which has distinctive genetic and phenotypic characteristics. Genomic resources are essential to understand the current status of these species, but due to the large size of their genomes (about 16 to 20 Gb), it is not easy to analyze. To reveal the genomic characteristics of these species, we constructed more than ten thousands of protein-coding gene sequences from multiple samples of each species, using the de novo transcriptome assembly approach from RNA-Seq data, confirming their taxonomic relationship which was reported based on mitochondrial DNA and marker genes. Also, by comparing previously reported transcriptome of Hynobius chinensis and Hynobius retardatus, lived in China and Japan, respectively, we found that Korean species have unique genetic signatures. By comparing vertebrate model organism genes, we reported Hynobidaii specific proteins. These data would be a useful resource to study other Caudata species in the future. This research was supported by the National Institute of Biological Resources, Republic of Korea, under the project "Genetic diversity of animal resources” (NIBR201703203 and NIBR201803101).

Project description:The giant panda (Ailuropoda melanoleuca) stands as a flagship and umbrella species, symbolizing global biodiversity. While traditional assisted reproductive technology faces constraints in safeguarding the genetic diversity of giant pandas and bolstering the population size of giant pandas, induced pluripotent stem cells (iPSCs) known for their capacity to differentiate into diverse cells types, including germ cells, present a transformative potential for conservation of endangered animals. In our study, we isolated primary fibroblast cells from an individual giant panda and successfully generated giant panda induced pluripotent stem cells (GPiPSCs) through a non-integrating episomal vectors reprogramming method. Characterization of these GPiPSCs revealed their state of primed pluripotency and demonstrated their potential for differentiation. Furthermore, we innovatively formulated a species-specific chemically defined FACL medium and unraveled the intricate signaling pathway networks responsible for maintaining the pluripotency and fostering cell proliferation of GPiPSCs. This study provides key insights into rare species iPSCs, offering materials for panda characteristics research and laying the groundwork for in vitro giant panda gamete generation, potentially aiding endangered species conservation.
Project description:We sampled lake-type and riverine sockeye in the pristine natural habitats of Aniakchak National Monument and Preserve, Alaska USA. Samples were taken on the same day and close proximite in time. We sampled 17 riverine individuals from Albert Johnson Creek and 13 individuals from Surprise Lake. cDNA from a single individual on the Cy5 was compared with a reference of aRNA on the Cy3.
