Definitions
- the present invention relates to the technical field of the conservation of living cells. More specifically, the invention relates to a new medium for the conservation of organs, biological tissues or living cells, in particular living human corneas.
- organ transplants when an organ is removed from a donor, with a view to being grafted onto a recipient, it is necessary to have an organ preservation medium capable of maintaining its vitality for good graft taken. In fact, quite often, different media are needed.
- a transport medium is generally used for transporting the corneas from the sampling site to the culture center, on the one hand, and from the culture center to the graft site, on the other hand hand, - a medium of conservation.
- This medium must guarantee optimal conservation of the cell viability in the medium term, that is to say approximately 4 to 5 weeks, maximum security in terms of quality (endothelial control ), sterility (bacteriological, serological and virological controls), and - a deturgescence medium, used approximately 24 hours before the transplant, in order to reduce the thickness of the cornea and make it transparent.
- Most of the media currently used contain components of animal origin: fetal calf albumin serum, protein of animal origin such as transferrin, insulin, etc. Due to the presence of components of animal origin in these media, it is difficult to guarantee their health security with regard to prion diseases, in particular Creutzfeld Jacob's disease.
- the present invention aims to provide a new preservation medium preserving the viability of living cells.
- Another objective of the invention is to provide a conservation medium at low cost, due to the components it contains.
- the preservation medium according to the present invention must also have maximum security in terms of quality and sterility.
- it has the advantage of being able to be prepared from entirely synthetic components, that is to say from chemical and recombinant synthesis, therefore non-immunogenic and not contaminated with infectious agents. Consequently, the preservation medium according to the invention may have a defined composition reproducible from one batch to another.
- the invention relates to a medium for preserving organs, biological tissues or living cells containing a liquid nutritive base, characterized in that it contains a high molecular weight hyaluronic acid and sodium chloride and in that that it does not contain any component of animal origin.
- the invention also relates to the use of such a medium for the conservation, organoculture, cell culture, transport or deturgescence of organs, biological tissues or living cells and in particular living human corneas .
- living biological organs, cells or tissues is meant components of human or animal origin comprising fibroblasts, endothelial cells and / or living epithelial cells.
- the storage medium of the invention can be qualified as an additional therapeutic product.

- the preservation medium contains a chemical nutritious aqueous base, conventionally used in organ preservation or cell culture media.
- a chemical nutritious aqueous base conventionally used in organ preservation or cell culture media.
- Certain cells in addition to the 13 essential amino acids, have specific needs (serine, for example, for lymphoid cells); - sugars, glucose is most generally used, although it can be replaced by galactose when it is necessary to limit the accumulation of lactic acid; - vitamins, mainly from group B, 8 of which are considered essential; - ions, provided in the form of balanced saline solutions, which play an important role in maintaining the membrane potential and the osmotic pressure, they are also the cofactors of many enzymatic reactions; - metals present in trace amounts, seem to play an increasingly important role, in particular when the culture is carried out in a defined medium. The most important are selenium, cadmium and lithium. This type of base can be prepared from these various constituent elements.
- Certain chemical nutrient bases also exist commercially, either in liquid form or in solid form: the latter must then be reconstituted in water.

Indeed, on the one hand, unlike most of the media used to date for the preservation of organs, biological tissues or living cells, the medium according to the invention contains neither fetal calf albumin serum, nor lactorefin , transferin, insulin, and other proteins of animal origin. On the other hand, high molecular weight hyaluronic acid and methylcellulose are used, the synthesis of which does not involve any raw material of animal origin. Such a preservation medium can therefore easily comply with the legislation on additional therapeutic products defined in article L. 1263-1 of the Public Health Code. The use of a preservation medium free of animal components makes it possible to improve the health safety of the preserved cells.

- the corneal thickness is measured at the apex by ultrasonic pachymetry (Tomey AL-2000, Tokyo, Japan).
- a third measurement of the DCE is carried out, this time after incubation for 45 seconds with alizarin red (Sigma) 4% in buffer phosphate pH 4.5 intended to color cell membranes.
- This non-vital staining can only be used at the end of storage due to its cellular toxicity. The entire procedure is carried out blind regarding the nature of the conservation environment.
- the two preservation and deturgescence media are packaged in the same containers (125 ml Nalgene bottle) and numbered by a person who does not take part in either the preservation or the DCE determinations. A numbering system based on a randomization list makes the allocation of media unpredictable according to the numbers on the bottles.
- DCE measurement procedure After rinsing the cornea with BSS (“Balanced Sait Solution”, Alcon, Kaysersberg, France), the endothelium is covered for 1 minute with 0.4% trypan blue (Sigma), then rinsed for 4 minutes with 0.9% sodium chloride ”. The corneal endothelium is then observed at x10 magnification under an optical microscope coupled to the prototype endothelial mosaic analyzer described by Gain P. et al. in Br J Ophthalmol 2002, 86, pages 306-11 and 531-6. Ten images of distinct areas of the endothelium are captured and archived on the hard drive for delayed analysis. This analysis covers each time more than 300 cells.
