ABSTRACT
According to literature, certain microorganism productions mediate biological effects. However, their beneficial characteristics remain unclear. Nowadays, scientists concentrate on obtaining natural materials from live creatures as new sources to produce innovative smart biomaterials for increasing tissue reconstruction in tissue engineering and regenerative medicine. The present review aims to introduce microorganism-derived biological macromolecules, such as pullulan, alginate, dextran, curdlan, and hyaluronic acid, and their available sources for tissue engineering. Growing evidence indicates that these materials can be used as biological material in scaffolds to enhance regeneration in damaged tissues and contribute to cosmetic and dermatological applications. These natural-based materials are attractive in pharmaceutical, regenerative medicine, and biomedical applications. This study provides a detailed overview of natural-based biomaterials, their chemical and physical properties, and new directions for future research and therapeutic applications.

In order to adapt to the rapid development of experimental techniques in the field of cell molecular biology, to quickly and effectively cultivate the experimental skills of postgraduates, systematic reforms should be carried out on advanced cellular molecular biology skill experiment teaching. The combi-nation of basic theory, biological experiment and practical application enables students to master the basic techniques from drawing materials to molecular biology analysis and construct in vitro transgenic cell model. Adding clinical case analysis, simulated ethical review and other lively classroom activities, which can help students carry out scientific research as soon as possible, improve students' interest and cultivate students' teamwork ability. The teaching effect is good and worth promoting.
