AI-Driven Predictive Modeling and Optimization of Hydrogel-Based Biomaterial and Stem Cell Formulations for Enhanced Skin Tissue Regeneration and Chronic Wound Healing Ref.No.SSTCRC2642
1. Introduction
Chronic wounds and significant skin injuries represent a major clinical challenge with substantial socioeconomic burdens. Current tissue engineering strategies often rely on iterative experimental approaches to design biomaterial scaffolds and cell-based therapies, which are time-consuming, costly, and suboptimal. Hydrogel biomaterials loaded with stem cells/their secretions have shown great promise in promoting host tissue response and regeneration. However, predicting and optimizing key parameters, such as hydrogel composition, biomaterial concentration, stem cell type, seeding density, conditioned medium concentration and release kinetics, to elicit the desired therapeutic outcome remains a complex, multivariate problem. Artificial intelligence (AI) and machine learning (ML) offer a transformative opportunity to model these complex biological-material interactions, predict healing outcomes, and accelerate the design of optimal regenerative therapies.
2. Research Progress
Remaining Phases:
-Expanded Data Generation: Conduct a systematic in-vitro study to generate a robust, high-quality dataset. This will involve testing a designed matrix of hydrogel compositions (varying polymer ratios, crosslinking densities) combined with different stem cell types (e.g., mesenchymal stem cells, adipose-derived stem cells) at multiple loading densities.
-AI Model Development & Training: Develop and train specialized ML models using the combined public and proprietary datasets. The goal is to create a predictive tool that correlates input parameters (material/cell variables) with output performance (e.g., cell viability, proliferation, cytokine secretion, in-vivo healing scores from literature).
-Model Validation & Optimization: Validate the AI model's predictions using a new set of in-vitro experiments. Employ the model in an iterative feedback loop to suggest the most promising "next experiment" for optimization, aiming to identify 2-3 top candidate formulations.
-Pre-Clinical Proof-of-Concept: Translate the top AI-optimized formulation into a standardized product prototype. Initiate a pilot in-vivo study using a standardized chronic wound animal model to validate the therapeutic efficacy predicted by the AI model.
-Data Analysis, Publication, and IP Strategy: Analyze all data, prepare manuscripts, and file for intellectual property protection on the optimized formulation and the predictive AI platform.
3. Cooperation Required
This project primarily requires financial collaboration in the form of an international research grant. The funding is essential to cover:
· Personnel Costs: Salaries for a dedicated research assistant, a data scientist/AI specialist, and a postdoctoral fellow.
· Consumables & Materials: Costs for stem cell culture, hydrogel polymers, reagents, and animals for the in-vivo phase.
· Equipment Access & Fees: Fees for advanced characterization equipment (e.g., confocal microscopy, rheometry, sequencing) and high-performance computing resources for model training.
· Publication & Licensing Fees: Open-access publication costs and patent filing fees.
4. Benefits
Global & Regional (Asia) Impact:
-Clinical Translation: Accelerates the development of optimized regenerative therapies for chronic wounds, a growing burden due to diabetes and aging populations, especially in Asia.
-Paradigm Shift: Moves tissue engineering from trial-and-error to an AI-driven, predictive science, reducing development time, cost, and animal use globally.
-Economic & Healthcare: Lowers long-term treatment costs and disability burdens. Positions Asia as a leader in convergent biomedical AI, fostering innovation ecosystems and skilled jobs.
