Stem cell research holds revolutionary potential in regenerative medicine and therapeutic development. However, manual analysis of microscopic images of stem cells is often time-consuming, subjective, and prone to inter-observer variability. Deep learning offers a promising approach to automate and enhance the accuracy of this analysis. Objective: This literature review aims to explore and analyze the latest applications of deep learning in microscopic image analysis for stem cell research, with a focus on the techniques used, model performance, implementation challenges, and implications for the advancement of stem cell research and regenerative medicine. Methods: A systematic search was conducted in the PubMed, IEEE Xplore, and Scopus databases for peer-reviewed articles published between 2018-2023. Inclusion criteria encompassed studies that applied deep learning for stem cell image analysis. The selection process involved screening titles/abstracts and full-text reviews, with 50 articles selected for in-depth analysis. Results: The review identified various deep learning architectures, particularly Convolutional Neural Networks (CNNs) and U-Net, successfully applied for segmentation, classification, and tracking of stem cells. Studies showed an accuracy increase of up to 95% in detecting and characterizing induced Pluripotent Stem Cells (iPSCs), as well as a tenfold improvement in analysis time efficiency. Deep learning implementation also demonstrated potential in predicting stem cell differentiation and automating quality control. The main challenges include the need for large labeled datasets, model interpretability, and protocol standardization. Conclusion: The application of deep learning in stem cell image analysis demonstrates significant potential to accelerate and enhance the accuracy of research. Although technical and ethical challenges remain, integrating this technology has the potential to drive rapid advancements in regenerative medicine. Future research should focus on developing explainable models, integrating multi-modal data, and clinical validation.
