The present invention relates to a method for preserving urinary cells or cells from another body fluid, the method comprising the step of contacting a urine sample obtained from a patient with a buffer substance suitable to create and/or maintain a pH value in the range of 6 to 8, particularly approx. 7, within said urine sample, and a formaldehyde releasing compound.

An alcohol-free lotion for the topical application having antiseptic properties is made by combining an aqueous phase comprising formaldehyde and at least one humectant with an oil phase comprising at least one surfactant and at least one oil; wherein the at least one humectant is present in the aqueous phase in the range of from 30 to 75 wt. %., wherein formaldehyde is present in the aqueous phase in the range of from about 1.0 to 20.0 wt. %; wherein the surfactant is present in the oil phase in the range of from about 30 to 60 wt. %; wherein the aqueous phase to oil phase ratio is from about 10:1 to 4:1; and wherein the lotion free of the odor of formaldehyde.

The present invention relates to a process for preparation and cryopreservation of dental pulp teeth and products thereof resulting in innovative cellular systems useful for therapeutic application based on the mesenchymal stem cells, so called dental pulp stem cells (DPSCs).

The objective of this invention is to provide the most adequate cellular isolates from dental pulp tissue from a tooth of a human subject. Fast expanding populations of DPSCs can be obtained, while maintaining their chromosomal stability, and determined to present the phenotypical and functional characteristics desired of such populations.

In another aspect, the present invention provides a novel and simplified method increasing thSpece viability of the dental tissue during the storing and banking. Also, the isolation of DPSCs from these teeth is improved and herein disclosed.

Therefore, the present invention is in the field of cell-based therapies, regenerative medicine, and optimized processes for obtaining the desired cell-isolates.

An aspect of the present disclosure provides a solution for transporting or storing a body fluid sample, the solution including a substance selected from the group consisting of kanamycin, G418, streptomycin, maltotriose, N-acetylmuramic acid, and glucose as an active ingredient.
