System Science of Biological Dynamics database (SSBD:database) provides a rich set of open resources for analyzing quantitative data and microscocpy images of biological objects, such as singole-molecule, cell, gene expression nuclei, etc. Quantitative biological data and microscopy images are collected from a variety of species, sources and methods. These include data obtained from both experiment and computational simulation.


Microscopy Images

Calcium response and shape changes in oocyte of C. elegans

DIC image of nuclear division dynamics in C. elegans embryo

TEM image of retinal tissue from human embryonic stem cells

Quantitative Data

Nuclear division dynamics in D. rerio wild-type embryo

Nuclear division dynamics in C. elegans wild-type embryo

Single molecule dynamics in E. coli wild-type

    SSBD 2020 Update
    SSBD 2020 update, the metadata database fully renewed, and 77 image datasets (7GB) and 4 quantitative datasets are added. We are plaining next database update in a half year for COVID-19 situation.
