HumanTestisDB

HumanTestisDB is a comprehensive database for human testis, it consists of 46 single-cell sequencing datasets from human testis, covering ages from 6 weeks post-fertilization to 49 years old. After uniform analysis, a total of 131,113 cells were retained and classified into 38 different cell types. HumanTestisDB offers six cell sets, each focusing on critical biological events during spermatogenesis and providing in-depth cell type annotations. HumanTestisDB also elucidates cell-cell interactions within the testicular microenvironment across eight developmental stages, detailing the signaling pathways, receptor-ligand pairs, and the cell types involved in these interactions. In summary, HumanTestisDB provides invaluable insights into testicular transcriptomics and interactions, and serves as a vital tool for further research in reproductive biology.人类睾丸数据库（HumanTestisDB）是一款针对人类睾丸的综合型数据库，其收录了46组人类睾丸单细胞测序数据集，样本的发育跨度涵盖受精后6周至49岁。经统一标准化分析后，最终保留131,113个有效细胞，并将其归类为38种不同的细胞类型。该数据库提供六组细胞集，每一组均聚焦于精子发生过程中的关键生物学事件，并提供了详尽的细胞类型注释信息。此外，该数据库还阐明了八个发育阶段下睾丸微环境内的细胞间互作关系，详细解析了这些互作所涉及的信号通路、受体-配体对以及参与互作的细胞类型。总而言之，该数据库为人类睾丸转录组学及细胞互作研究提供了极具价值的研究视角，同时也为生殖生物学领域的后续研究提供了至关重要的工具支撑。
