The present invention relates to an in vitro method for creating a viable connective tissue and/or osseous tissue obtained by tribological solicitations of a biological culture. It further relates to a viable connective tissue and/or osseous tissue susceptible to be obtained by said method as well as to the use of said method or viable connective tissue and/or osseous tissue to prepare a biological implant.

Provided herein is technology relating to engineered tissues and particularly, but not exclusively, to methods, compositions, and systems for engineering a biosynthetic vascular network.

The present invention relates to a fibrocartilage preparation method and fibrocartilage prepared by the method.

A lung breathing chip and cell stretching culture platform and an operating method thereof are disclosed. The lung breathing chip and cell stretching culture platform controls the output of the motor by programming, stretches the micro-fluidic chip by the cam component, changes the size of the cam component and the frequency of the motor rotation to change the stretching frequency and the amount of stretching to simulate the breathing of the lungs in different states, uses liquid electrophoresis technology to arrange the cells in the biocompatible hydrogel and the hydrogel three-dimensionally to imitate the three-dimensional cell tissue, and injects drugs through the dynamic perfusion system to realize the drug testing platform that the cells of the chip bionic lung tissue are stretched.

The present invention relates to a microtissue compartment device, comprising a compartment structure (1) having an upper surface (2) and a lower surface (3) essentially coplanar thereto, and at least two wells (4) suitable for accommodating one or more microtissues (5) in a liquid volume, each well having a lower section (4a) with a given diameter, coaxially oriented thereto an upper section (4b) with an extended diameter, and at least one conduit (6) fluidically connecting at least two wells to one another, and at least one space (13) arranged above a well. At least one well has, in its upper section, a relief structure (9) that prevents spreading or overflow of a liquid volume comprised in said well into space (13).

Disclosed herein are scalable, modular bioreactor systems for efficient preparation of cell-based tissues. Also disclosed herein are methods, compositions, and apparatuses for preparing scaffolds.

The present invention relates to a biomimetic nerve chip for evaluating the efficacy and toxicity of a drug, a method for evaluating the efficacy of a drug on nerve cells through astrocytes by using the biomimetic nerve chip, and a method for evaluating the toxicity of a drug on nerve cells through astrocytes by using the biomimetic nerve chip, the biomimetic nerve chip comprising: an astrocyte supply unit and a nerve cell supply unit for simulating nerve tissue; and a culture solution supply unit for supplying a culture solution to the astrocyte supply unit and the nerve cell supply unit. By using the biomimetic nerve chip for evaluating the efficacy and toxicity of a drug provided in the present invention, it is possible to overcome inaccuracies due to differences between the different species in animal experiments in the study of nerve tissues, and using a combination of astrocytes and nerve cells enables use of the nerve chip as a platform to more accurately evaluate the efficacy and toxicity of a drug under conditions similar to in vivo conditions, and the nerve chip can be applied to studies of microenvironments in nerve tissues and other organ-on-a-chip studies. Therefore, the present invention may be utilized in the development of a human-on-a-chip that can effectively analyze the efficacy and toxicity of a drug.
