Identification and selection of different cartilage cell fractions of human or animal cartilage and intervertebral disk tissue, where a UV light source is used in a wavelength where the biology of the cell fraction converts the UV into visible light. The UV light has a wavelength of 375-440 nm, to illuminate the extracted cell sample by exposure or light through it. To give a trouble-free identification and selection of different cartilage cell fractions of human or animal cartilage and intervertebral disk tissue, a UV light source is used in a wavelength where the biology of the cell fraction converts the UV into visible light. The UV light has a wavelength of 375-440 nm and ideally 405 nm, to illuminate the extracted cell sample by exposure or light through it, for non-contact use for tissue engineering or replanting without compromising the sterility. The identification is through a microscope with a lens giving a 10-50 times enlargement. A robot, working through an electromechanical or electropneumatic or electrohydraulic or electrostatic system, separates the illuminated and non-illuminated tissue samples without damage, so that cell cultivation is possible. The tissue samples can be cleaned mechanically with a solution which does not affect their vitality, but removes blood, etc. The samples can be cut, with minimal damage to cells adjacent to the cut.
