Aging progressively affects the functioning of our body and, among other things, deteriorates the ability of the hematopoietic system- the set of organs and tissues responsible for producing blood cells- to maintain adequate blood cell production.
Detect what the eye does not see ChromAgeNet, an AI-based tool, identifies aging-associated patterns in hematopoietic stem cells by analyzing the 3D chromatin organization in microscopy images. Using a convolutional neural network, the model accurately distinguishes young from aged cells with a 77% probability, even when differences are not visible to the naked eye. It identified specific features such as chromatin entropy, peripheral heterochromatin, and certain chromatin condensates as key indicators of age. A new way to look for rejuvenation strategies The study highlights ChromAgeNet's potential as a screening tool for treatments that could reverse age-associated cellular characteristics. By testing it on aged hematopoietic stem cells treated with epigenetic drugs, the tool detected changes consistent with a younger state. This capability, combined with the low-cost DAPI staining and efficient model, enables high-throughput microscopy workflows, accelerating the search for cell rejuvenation strategies. The researchers also made their 3D image dataset and ChromAgeNet publicly available to foster further research.
