The invention relates to a method for collecting oral mucosa cells and/or cell fragments from patients (participants/persons), wherein the person or patient chews a water insoluble, non-digestible chewing mass, wherein the oral mucosa skin cells and/or DNA and/or RNA and/or the fragments thereof are taken up by the chewing mass during the chewing process and the taken up cells and/or cell fragments can be separated from the chewing mass after the chewing process has been completed. The cells/cell fragments can be used to obtain DNA, cell components, human cells, bacteria and viruses, and for other analytical purposes. |
