DETAILED DESCRIPTION OF THE INVENTION The invention was obtained from eggs of the Caucasian honey bee (Apis mellifera caucasica). It is a method for culturing isolated cells in an in vitro environment. The method collecting eggs in a sterile manner, performing the sterilization process, cells from eggs were enzymatically separated using a trypsin / EDTA solution. separation, centrifugation of the separated cells, and the resulting The cells are placed in a culture medium containing bee hemolymph extract, and the cells are stored at 34°C. Incubation at a certain temperature and in an environment containing 5% CO₂ stimulated cell proliferation. microscopic monitoring and passage of the culture at specific intervals It includes. Within the scope of the invention, Caucasian honey was used as the starting material for cell culture. Bee eggs are used. The eggs are used in cell culture. They are collected under sterile conditions to prevent contamination. Egg collection and subsequent cell culture processes are performed in a sterile laminar flow cabinet. This is carried out within it. Thus, during the preparation of the cell culture... This ensures that the access of environmental microorganisms to the culture is limited. The collected eggs are sterilized before being cultured. It is kept in place. 70% ethanol and UV light are used in the sterilization process. The sterilization process takes 20 minutes. This process sterilizes the eggs. 2 Maintaining the sterility of the culture before the cell separation stage. It is being prepared as follows. Separation of cells from eggs after sterilization process. This is carried out using a 0.05% trypsin / EDTA solution for cell separation. Eggs are washed with a 0.05% trypsin / EDTA solution for 5 minutes. It undergoes enzymatic decomposition. The use of trypsin / EDTA solution. the cells in the egg material can be separated from each other and transferred to culture. The cell suspension is obtained. Material containing cells obtained after enzymatic decomposition process. It is subjected to centrifugation. The centrifugation process takes place at a speed of 1500 rpm for 5 minutes. This is carried out. Thus, the cells obtained after enzymatic decomposition are processed. It is separated in order to be transferred to the cultural environment. The cells obtained after centrifugation are transferred to a culture medium. The culture medium used in this invention is primarily L-15 medium. The L-15 medium in question contains 10% FBS and 5% bee hemolymph extract. This is supported. A combination of L-glutamine and antibiotics is also used in the culture medium. It is located. FBS promotes the viability and proliferation of cells in culture medium. It is used in the support of honey bee hemolymph extract, culture medium. It ensures that the cells are supported in a way that meets their needs. L- Glutamine is one of the nutritional components of cell culture medium. The antibiotic combination, on the other hand, prevents microbial contamination during cell culture. It is used for the purpose of limiting [the use of] L-15 medium, 10% FBS. Culture containing a combination of 5% bee hemolymph extract, L-glutamine, and antibiotics. the environment, the viability of isolated Caucasian honeybee cells under in vitro conditions and It creates a culture medium in which proliferation is supported. The cells taken into the culture medium are placed in an incubator. The incubation process... The culture is carried out at a constant temperature of 34°C and in a medium containing 5% CO₂. The pH of the environment is regulated to 6.6. In this way, the cells are treated with Caucasian honey. at temperature and pH conditions determined according to the physiological conditions of the bee is being held. The condition of the cells in the culture medium during incubation is observed microscopically. is being monitored. Microscopic examination is performed at 200x magnification and 3 The morphological characteristics of the cells and their proliferation within the culture are monitored. This By monitoring, the development of cells in the culture medium is tracked. The cells that proliferate in culture are passaged at intervals of 3-4 days. Passaging is performed in this way... The continued growth of cells present in the existing culture in the new culture medium This ensures that the eggs of Caucasian honeybees are initially produced. the continuation of the proliferation of the obtained cells in the culture medium and the cells The aim is to ensure the continuity of the culture. The bee hemolymph extract used in the invention is a culture medium for Caucasian honey. in a way that supports the nourishment and multiplication of cells obtained from the bee It is one of the components created. The ratio of bee hemolymph extract in the culture medium. It is determined as 5%. FBS, on the other hand, is present at a rate of 10% in the culture medium. This The viability of cells under culture conditions with two components L-15 medium and It creates an environment that supports its proliferation. The 0.05% trypsin / EDTA solution used within the scope of this invention is for eggs. It enables the separation of cells from the material. Enzymatic separation 5 With a time limit of only minutes, it is suitable for transferring cells to the culture medium. The cell suspension is obtained. Within the scope of the invention, the temperature is 34°C and the pH value of the culture medium is 6.6. These temperature and pH conditions are determined for in vitro culture of the cells. It creates the physiological conditions in which the child is kept in the incubation environment. The incubation environment also... It contains 5% CO₂.
