Electronic cigarette tobacco liquid containing stem cell exosome and preparation method and application thereof

Abstract

The invention discloses an electronic cigarette tobacco liquid containing stem cell exosome and a preparation method and application thereof, and relates to the field of electronic cigarettes. The electronic cigarette tobacco liquid containing the stem cell exosome is prepared from, by mass, 65%-80% of propylene glycol, 1%-2% of spices, 15%-20% of glycerin and 5%-15% of water, and the electronic cigarette tobacco liquid further contains the umbilical cord mesenchymal stem cell exosome, wherein the content of the umbilical cord mesenchymal stem cell exosome is 1 mg / g. The propylene glycol, spices, glycerin and water are mixed and added with the umbilical cord mesenchymal stem cell exosome, so that the electronic cigarette tobacco liquid containing the stem cell exosome is obtained. The stem cell exosome of the electronic cigarette tobacco liquid containing the stem cell exosome is absorbed into a body after being atomized by an electronic cigarette. Mesenchymal stem cells are from a umbilical cord and obtained through primary culture and subculture after being separated and extracted from the umbilical cord. According to the application of the electronic cigarette tobacco liquid containing the stem cell exosome, the stem cell exosome of the electronic cigarette tobacco liquid containing the stem cell exosome can directly enter lung tissue in an atomized mode to improve functions of a lung.

Description

technical field [0001] The present invention relates to electronic cigarettes, in particular to an electronic cigarette liquid containing stem cell exosomes used in improving lung function by adding exosomes of umbilical cord mesenchymal stem cells, and a preparation method and application thereof. Background technique [0002] E-cigarettes, also known as electric atomized cigarettes, are electronic devices that transmit e-cigarette liquid to the respiratory system by means of electronic heating. Electronic cigarettes are mainly composed of cigarette rods (including components such as light-emitting diodes, batteries, control circuits, pneumatic switches, and atomizers) and cartridges (including liquid storage chambers and suction nozzles). When smoking the electronic cigarette, the pneumatic induction switch is triggered under the negative pressure of the suction, the integrated control circuit is connected through the electromagnetic induction, the indicator light is on, a...
