Background:

Tissue engineering offers an alternative to organ transplantation.
Developing injectable, biodegradable materials is crucial for clinical applications.

Purpose of the Study:

To develop and evaluate a novel injectable biomaterial for tissue engineering.
To assess the biocompatibility and in vivo performance of a polycaprolactone and sebacic acid blend.

Main Methods:

Prepared an injectable blend of polycaprolactone (PCL) and sebacic acid.
Evaluated in vitro biocompatibility and mesenchymal stem cell differentiation.
Assessed in vivo subcutaneous and bone implantation in rats for tissue formation and degradation.

Main Results:

The PCL-sebacic acid blend demonstrated in vitro biocompatibility.
The material promoted mesenchymal stem cell differentiation.
In vivo studies showed adequate degradation rates and promoted tissue regeneration without adverse reactions.

Conclusions:

The novel injectable biomaterial is biocompatible and suitable for bone tissue engineering.
The blend effectively promotes tissue regeneration in vivo.
This material holds potential for future cell and gene therapies.
