Composition for preventing or treating liver diseases, containing plant stem cell lines derived from the cambium of
View Patent ↗The present invention relates to a composition for preventing or treating liver diseases, which contains, as an active ingredient, any one or more of a homogeneous cell line derived from the cambium of Panax ginseng , including wild ginseng or ginseng, a lysate thereof, an extract thereof and a culture medium thereof. The homogeneous cell line according to the present invention, a lysate thereof, an extract thereof and a culture medium thereof have minimized side effects compared to existing agents for treating liver diseases, and thus are safe for the human body. Also, they can increase the levels of s-antibody (HBsAb) and e-antibody (HBeAb) against hepatitis virus and inhibit the proliferation of hepatitis virus, and thus they are useful for the prevention and treatment of liver diseases. In addition, they have the effect of lowering the levels of liver injury, and thus are useful as a functional food for improving liver function.
1. A method of treating liver diseases, comprising administering a composition comprising a cell line to a patient, wherein the cell line is derived from a cambium of Panax ginseng by culturing cambium-containing storage root tissues of Panax ginseng while applying osmotic stress to the cambium-containing storage root tissue during, before or after the culture and has the following characteristics:
a. it is in an innately undifferentiated state; and
b. it is a homogeneous cell line.

a. it exists at single cell level during suspension culture;
b. it has low sensitivity to shear stress in a bioreactor compared to cell lines derived from tissues other than the cambium of Panax ginseng ; and
c. it has a higher growth rate and is cultured more stably compared to the cell lines than those cell lines derived from tissues other than the cambium of Panax ginseng .
3. The method according to claim 1 , wherein the cell line is obtained using an isolation method comprising the following steps of:
a. obtaining a tissue containing the cambium of Panax ginseng ;
b. culturing the obtained cambium-containing tissue in a medium containing indole-3-acetic acid (IAA) or indole-3-butyric acid (IBA), thereby inducing a cambium-derived cell line, wherein osmotic stress is applied to the cambium-containing storage root before, during or after the culturing; and
c. collecting the induced cambium-derived cell line.

5. The method according to claim 1 , wherein the liver diseases is any one among hepatitis, liver cancer, liver cirrhosis, fatty liver and toxipathic liver diseases.
6. A method of improving liver function, comprising orally administering functional food containing a cell line, wherein the cell line is derived from a cambium of Panax ginseng by culturing cambium-containing storage root tissue of Panax ginseng while applying osmotic stress to the cambium-containing storage root tissue during, before or after the culture and has the following characteristics:
a. it is in an innately undifferentiated state; and
b. it is a homogeneous cell line.
7. The method according to claim 6 , wherein the cell line is additionally characterized in that:
a. it exists at single cell level during suspension culture;
b. it has low sensitivity to shear stress in a bioreactor compared to cell lines derived from tissues other than the cambium of Panax ginseng ; and
c. it has a higher growth rate and is cultured more stably compared to the cell lines than those cell lines derived from tissues other than the cambium of Panax ginseng .
8. The method according to claim 6 , wherein the cell line is obtained using an isolation method comprising the following steps of:
a. obtaining a tissue containing the cambium of Panax ginseng ;
b. culturing the obtained cambium-containing tissue in a medium containing indole-3-acetic acid (IA) or indole-3-butyric acid (IBA), thereby inducing a cambium-derived cell line, wherein osmotic stress is applied to the cambium-containing storage root before, during or after the culturing; and
c. collecting the induced cambium-derived cell line.
9. A method of inhibiting proliferation of hepatitis virus, comprising administering a composition comprising a cell line to a host infected with hepatitis virus wherein the cell line is derived from a cambium of Panax by culturing cambium-containing storage root tissue of Panax ginseng while applying osmotic stress to the cambium-containing storage root tissue during, before or after the culture and has the following characteristics:
a. it is in an innately undifferentiated state; and
b. it is a homogeneous cell line.
10. The method according to claim 9 , wherein the cell line is additionally characterized in that:
a. it exists at single cell level during suspension culture;
b. it has low sensitivity to shear stress in a bioreactor compared to cell lines derived from tissues other than the cambium of Panax ginseng ; and
c. it has a higher growth rate and is cultured more stably compared to the cell lines than those cell lines derived from tissues other than the cambium of Panax ginseng .
11. The method according to claim 9 , wherein the cell line is obtained using an isolation method comprising the following steps of:
a. obtaining a tissue containing the cambium of Panax ginseng ;
b. culturing the obtained cambium-containing tissue in a medium containing indole-3-acetic acid (IAA) or indole-3-butyric acid. (IBA), thereby inducing a cambium-derived cell line, wherein osmotic stress is applied to the cambium-containing storage root before, during or after the culturing; and
c. collecting the induced cambium-derived cell line.
12. A method for increasing the level of antibody against hepatitis virus, comprising administering a composition comprising a cell line to a host infected with hepatitis virus wherein the cell line is derived from a cambium of Panax ginseng by culturing cambium-containing storage root tissue of Panax ginseng while applying osmotic stress to the cambium-containing storage root tissue during, before or after the culture and has the following characteristics:
