Author Spotlight: Optimization of Ultrashort Peptide Matrices for Colorectal Cancer Organoids

Our research aims to evaluate ultrashort self-assembling peptides as matrices for Colorectal Cancer Organoid Cultures. We address questions about organoid morphology, for viability, proliferation, and the adhesion and the impact of biofunctionalization. The goal is to optimize peptide matrix compositions for effective organoid growth, and to contribute to regenerative medicine.

Cutting-edge technologies in our field involve 3D bioprinting for precise organic fabrication, microfluidic platforms for dynamic culture environments, and advanced imaging tools like atomic force microscopy and multiphoton microscopy. CRISPR-Cas9 gene editing refines genetic modification, while single cell RNA sequencing provides in-depth molecular insights. Current experimental challenges include enhancing organoid reproducability, refining vascularization for larger constructs, and mimicking complex tissue architecture.

Overcoming these limitations in long-term culture and incorporating immune components into models are active areas. Achieving standardized protocols and addressing ethical concerns opposing ongoing challenges in this field. Significant findings in our field include demonstrating the suitability of ultrashort self-assembling peptides for organoid cultures.

We have shown the versatility, reproducability, and stability of these peptides, providing a platform for fine tuning micro-environments. This contributes to advancing organoid-based studies, regenerative medicine, and biofunctionalized hydrogel research. Our protocol bridges and research gap, whereby providing a systematic approach to evaluating organoids in ultrashort self-assembling peptide matrices.

It addresses the need for standardized methods in assessing cell behavior within these matrices, aiding in durational design of peptide-based hydrogels for optimal organoid growth and advancing regenerative medicine studies.
