## Exhibit 99.1

**Exhibit 99.1**

**CollPlant's rhCollagen-Based BioInk Demonstrates Strong <br> Performance Compared to Matrigel® in Study Conducted by<br> Technion – Israel Institute of Technology**

● A head-to-head study by Israel's Technion found that CollPlant's rhCollagen-based bioink, **Collink.3D™**, outperformed **Matrigel®**, a leading extracellular matrix, in supporting structured tissue formation.

● The findings suggest **Collink.3D™** could offer a consistent, tunable, and animal-free alternative for advanced tissue engineering and research applications.

● Extracellular matrices are key tools in drug discovery, regenerative medicine, and tissue modeling. CollPlant's plant-based technology provides a sustainable and ethical approach without compromising performance.

REHOVOT, Israel, October 20, 2025 – CollPlant Biotechnologies (Nasdaq: CLGN), a regenerative and aesthetic medicine company developing innovative technologies and products based on its proprietary recombinant human collagen (rhCollagen), today announced positive results from a head-to-head comparative study of its rhCollagen-based bioink, **Collink.3D™**, and **Matrigel®**, conducted by the Levenberg Lab at Technion - Israel Institute of Technology.

**Matrigel®**, developed and marketed by **Corning**, has been one of the most widely used extracellular matrices for more than three decades. Derived from the Engelbreth-Holm-Swarm (EHS) mouse sarcoma, it contains a rich combination of basement membrane proteins such as laminin, collagen IV, heparan sulfate proteoglycans, and entactin/nidogen, as well as growth factors that make it a cornerstone for 3D cell culture, disease modeling, and drug discovery.

In the Technion study, **Collink.3D™** demonstrated enhanced mechanical strength, elasticity, and stability, providing a reproducible environment that supports organized and long-lasting tissue formation. These results suggest that **Collink.3D™** may serve as a next-generation, animal-free extracellular matrix, offering a complementary approach to traditional matrices such as **Matrigel®**.

The global market for basement membrane matrices, including Matrigel and similar products, was valued at approximately $96 million in 2024 and is projected to reach $201 million by 2031, growing at a CAGR of 11.2%. Key suppliers include Corning, Thermo Fisher Scientific, and R&D Systems, which collectively account for more than 69% of market share.

Yehiel Tal, Chief Executive Officer of CollPlant, commented: "We are very pleased with the outcome of this study by the Technion. The results reinforce Collink.3D™ as a biologically supportive and durable bioink that promotes cell organization and tissue development while maintaining structural integrity over time. We believe Collink.3D™ represents a strong, animal-free alternative for tissue engineering, regenerative medicine, and drug discovery applications."

**About Collink.3D™**

Collink.3D™ is a recombinant human type I collagen methacrylamide bioink, produced using genetically engineered plants and free of any animal-derived substances or reagents. It is the first and only plant-based human-collagen bioink platform, designed to closely mimic the native properties of human tissues and organs.

Collink.3D™ enables scalable and reproducible biofabrication of 3D tissue and organ models, including disease models for drug screening and therapeutic research, as well as scaffolds, tissues, and organs intended for implantation. It supports the creation of complex 3D architectures with defined geometric, physical, and biological properties - offering a sustainable and high-performance solution for the rapidly growing field of regenerative medicine.
