Bioprinting Scaffold Material Science (Specifically Hydrogels and Decellularized Extracellular Matrix)

# Bioprinting Scaffold Material Science (Specifically Hydrogels and Decellularized Extracellular Matrix)

## Core Concepts & Introduction

Bioprinting relies heavily on the selection and engineering of scaffold materials, often referred to as bioinks. These materials provide temporary support for cells, guiding tissue formation and ultimately degrading to leave behind functional tissue. This knowledge pack focuses on two prominent classes: hydrogels and decellularized extracellular matrix (dECM).

**Why these materials?**
*   **Hydrogels:** Mimic the native ECM's high water content, providing a favorable environment for cell survival and proliferation.  Tunable mechanical and degradation properties. Relatively easy to synthesize and modify.
*   **dECM:**  Provides a naturally complex biochemical and biophysical environment, containing native growth factors and structural proteins.  Promotes cell-specific behavior and integration.
