The application belongs to the field of stem cell biology and relates to a culture method of a 3D nerve immune organoid containing microglia cells, which comprises the following steps: S1, inducing induced pluripotent stem cells in ectoderm direction and mesoderm direction respectively to obtain nerve-like embryoid bodies and yolk sac-like embryoid bodies; S2, culturing the nerve-like embryoid bodies to make them differentiate into nerves to obtain nerve ring structures, re-digesting the nerve ring structures to obtain nerve progenitor cell single cells, and culturing the yolk sac-like embryoid bodies to make them generate macrophage progenitor cells; and S3, fusing the nerve progenitor cell single cells and the macrophage progenitor cells and continuing to culture to form the 3D nerve immune organoid containing microglia cells. The brain-like organoid of the application can realize the following functions: exploring the control of microglia cells on the proportion of progenitor cells in the development stage, the change of phagocytosis, the control on the number of mature neurons, the influence on cell proliferation and apoptosis, and simultaneously accepting external stimulation and making corresponding functional stress changes.

This invention relates to the field of automotive parts technology, and discloses an automotive trim component with a transparent, seamlessly integrated lidar sensor and its manufacturing method. The trim component includes: a connected trim body, a mounting frame, and a lidar sensor. The trim body is disposed on the side of the mounting frame away from the lidar sensor and is connected to the mounting frame. The trim body includes a main body and a shielding coating covering the main body, with the shielding coating located on the side of the main body closer to the mounting frame. The main body is made of transparent plastic. The trim body has a lidar window area directly opposite the lidar sensor. A filter layer is provided along the lidar window area on the trim body. The filter layer allows light of a preset wavelength to pass through and filters light of other wavelengths. The advantages of this invention are that the automotive trim component is easy to manufacture, low in cost, and has a neat lidar window boundary.
