Abstract: A method for predicting and evaluating the function of a biomaterial includes (1) in the environment of a material to be tested, culturing human bone marrow mesenchymal stem cells; (2) collecting the human bone marrow mesenchymal stem cells cultured in step (1), extracting total RNA, performing purification, building a library, and sequencing a transcriptome to obtain transcriptome data of samples to be tested; and (3) subjecting the transcriptome data of the samples to be tested obtained in the step (2) to batch effect correction and feature extraction, and then inputting the resulting data to a function prediction and evaluation model of the present invention, and calculating the samples to be tested as confidence coefficients of different cell types respectively. The present invention can be used in the field of biomaterial function prediction and evaluation.
