Definitions
- This invention relates to a two component fibrin-glue com ⁇ position comprising the components A and B for improving in vitro fertilization.
- component A comprises fibrinogen and a protease in ⁇ hibitor
- component B comprises a proteolytic enzyme being capable of cleaving specifically fibrinogen and causing formation of the fibrin polymer and
- ingredients for culturing embryonic cells of mamals in one or both of the components A and B.
- cryoprecipitate of whole blood or plasma is used as fibrinogen containing fraction of component A.
- commercially available cryoprecipitate can be used. It can be advantageous to concentrate the cryoprecipitate between a factor 2 and 5.
- the cryoprecipitate is virus inactivated.
- a procedure for virus inactivation is, for example, described in PCT/EP 91/00503.
- the basic principle of this method is the treatment of the cryoprecipitate with special detergents and removing the detergent later on from the cryoprecipitate.
- the protease inhibitor present in component A is aprotinin and present in concentrations up to 10,000 U/ml based on total volume of component A.
- Aprotinin is com- shoutally available under the trademark Trasylol or Antagosan .
- tranexamic acid [4- (aminomethyl)cyclohexane carboxylic acid] or its acceptable salts is a suitable agent which can be used instead of aprotinin or in combination with.
- the second component B of the two component fibrin-glue composition of the invention is prepared by solution of proteolytic enzyme being capable of cleaving specifically fibrinogen.
- proteolytic enzyme being capable of cleaving specifically fibrinogen.
- thrombin has been used which was isolated from plasma of human beings or mamals such as bovine.
- the thrombin can be delivered in a lyophilized form.
- the reconstitution of thrombin occurs with a solution containing calcium chloride.
- concentration of the prote ⁇ ase specifically for the cleavage of fibrinogen depends on the method of transferring the embryo into the uterus.
- the concentration of thrombin should be lower whereas if a fast working fibrin glue is desirable the concentration of thrombin should be higher (fast fibrin- glue) .
- concentration range of thrombin is 0.4 to 4 units/ml in a slow working fibrin-glue.
- fibrin-glue of the present invention comprises as component B a proteolytic enzyme which is isolated from snake venom.
- the snake venom enzyme batroxobin which can be isolated from the south american pit viper Bothrpos moujini can be used. Chemically this venom is a single chain glyco peptide with a molecular weight of approximately 36,000. It is known under the name Defibrase which causes cleavage of the ala-16-arg/l7 glue bond in fibrinogen which causes the release of fibrino peptide A and the formation of monomeric fibrin I.
- the use of any venom converting fibrinogen to fibrin such as Defibrase or Reptilase is preferred when the cryo ⁇ precipitate is made from autologous source and the use of the venom will avoid the use of human blood product.
- ingredients for culturing embryonic cells of mamals in the fibrin-glue of the invention there must be present ingredients for culturing embryonic cells of mamals in the fibrin-glue of the invention. This can be achieved either by admixing the ingredients into one or both of the components A and B of the invention or dissolve these ingredients in a liquid and mixing this liquid to one or both of components A and B.
- Preferred ingredients for culturing embryonic cells of mamals are those comprising calcium chloride, potassium chloride, magnesium sulfate, sodium chloride, sodium bi ⁇ carbonate, sodium dihydrogenphosphate, D-glucose as well as phenol.
- the solution has a pH of about 7.2. It can be advantageous to add additionally pyruvic acid and antibiotics, e. g. gentamycin.
- EBSS is the abbreviation for Earle's Balanced Salt Solutions. It can be purchased in liquid or powder form. The liquid contains anhydrous calcium chloride in amounts of 0.2 g/1, potassium chloride 0.4 g/1, MgSO. x 7 H 2 0 0.2 g/1, sodium chloride 6.8 g/1, sodium bicarbonate 2.2 g/1, NaH PO.
- the respective powder form contains after being dissolved in one liter 0.20 g/L calcium chloride anhydrous, 0.4 g/1 sodium chloride, 0.0977 g/1 magnesium sulfate anhydrous, sodium chloride 6.80 g/1, NaH 2 P0. x H 2 0 and the same D-glucose and phenol red content as in the liquid form. It can be advantageous to add pyruvic acid preferably in amounts of 0.015 g/1 and gentamycin in amounts of 50 mg/1.
- the medium can be modified in order to meet the special requirements which may be differ, for example, with respect with agricultural applications such as breeding.
- the above mentioned culture medium can be used also in human in vitro fertilization.
- the advantage of the present fibrin-glue over the known fibrin-glue products having failed to improve the outcome of in vitro fertilization may be due to its increased anti- fibrinolytic activity preventing or postponing the embryo from one hand in the uterus on the other hand to degredate the clot.
- the two component fibrin-glue composition of the present invention enables the embryo to survive in the environment of the uterus before it is lodged and permenently fixed to the uterus wall. The surviving is supported by the medium containing ingredients for embryo cell culturing. Sur ⁇ prisingly, the high amounts of protease inhibitor like aprotinin do not interfere with the embryo but prevent the digest of the glue.
- the two component fibrin-glue com ⁇ position is iso-osmolar. Therefore, the disadvantage of the glues of the prior art being hyper-osmolar is prevented. Hyper-osmolarity causes the death of the embryo by drying out phenomena.
- the advantageous features of the fibrin-glue of the invention are the presence of salts and nutrients which are important for in vitro growing of the embryo, it contains anti- fibrinolytic activity to postpone the early degradation of the glue either by embryo or by the uterus. Moreover, the antifibrinolytic potency of the embryo has to be balanced to the extent that it will enable the fetus to lyse a certain area around itself creating a halo like shape of fluid surrounded by the fibrin-glue.
- cryoprecipitate as a source of fibrinogen rather than a fibrinogen concentrate is advantageous since the former one contains ingredients like fibronectin, von Wille- brand factor etc. which may be important for adhesion. Moreover, a cryoprecipitate may also contain other agents such as proteins or low molecular substances which support the development and lodging of the embryo. Also compounds having wound healing properties such as hyaluronic acid can be used.
- cryoprecipitate is dissolved in culture medium as described above. Then aprotinin or tranexamic acid is added to the cryoprecipitate.
- concentration of aprotinin in the cryoprecipitate containing component A is preferably in the range of 6,000 to 10,000 u/ml.
- the con ⁇ centration of tranexamic acid is preferably 10 - 200 ⁇ g/ml (final concentration) . This is equivalent to an aprotinin activity of about 3,000 to 10,000 KlU/ml.
- the final concen ⁇ tration of aprotinin in the mixture of component A and B is lower because of the dilution when component B is added.
- the dilution factor depends on the amount of component B which is added.
- the concentration of fibrinogen in the cryo ⁇ precipitate solution is relatively low compared with other fibrin-glues since there is no need for strong tensile strength. Preferred are concentrations of fibrinogen in the range of 5 to 20 g/1.
- the embryo is injected for example via the following method. The embryo is placed in the reconstituted cryoprecipitate solution in a culture dish. Then thrombin is added in con ⁇ centrations of 0.4 to 4 units. The thrombin concentration determines the clotting time of the glue, the embryo is sucked in the culture fluid and injected into the uterus.
