Today we will talk about liver cirrhosis and the process that precedes it – fibrosis.
Why does it occur? How to prevent cirrhosis? What to do if you have already been diagnosed with cirrhosis?
Why does fibrosis occur in the liver?
Liver fibrosis is the process of formation of excess connective tissue in the liver, which occurs in response to chronic damage to the organ. This process is a protective reaction of the body aimed at limiting damage, but with prolonged exposure to factors that damage the liver, it can lead to serious disruptions in organ function and the development of cirrhosis. The main causes of liver fibrosis:
1. Chronic viral infections
Hepatitis B and C: Long-term viral infections cause liver inflammation and damage to liver cells (hepatocytes). The body tries to restore damaged areas, but as a result of frequent damage and restoration, excess connective tissue is formed.
2. Alcoholic liver disease
Alcoholic hepatitis: Constant alcohol consumption leads to damage to liver cells and inflammation. Alcohol disrupts the liver’s metabolism, which contributes to the accumulation of toxic products and the formation of scar tissue.
3. Fatty liver disease (non-alcoholic fatty liver disease, NAFLD)
Non-alcoholic steatohepatitis (NASH): A condition in which fat accumulates in the liver and inflammation develops. It is often associated with obesity, type 2 diabetes, insulin resistance, and metabolic syndrome. Chronic inflammation leads to tissue damage and fibrosis.
4.Autoimmune Diseases
Autoimmune Hepatitis and Primary Biliary Cholangitis: In these cases, the immune system attacks the liver tissue, causing inflammation and damage to the liver cells. Chronic inflammation causes the buildup of connective tissue.
5. Toxic Exposure
Medicines and Chemicals: Long-term exposure to certain medications or toxins can damage liver cells, causing chronic inflammation and fibrosis.
Hepatotoxic Substances: Certain industrial chemicals and toxins can also cause liver damage.

6. Metabolic Disorders
Inherited Diseases: Conditions such as hemochromatosis (excess iron) and Wilson’s disease (copper buildup) can cause damage to liver tissue, leading to inflammation and fibrosis.
7. Biliary Diseases
Biliary Obstruction: Problems with the flow of bile can cause liver cell damage and inflammation, which in turn leads to fibrosis.
Mechanism of fibrosis formation:
When liver cells are damaged, hepatic stellate cells (Ito cells) are activated. They begin to transform into fibroblasts and produce collagen and other components of the extracellular matrix, which leads to the formation of scar tissue. At first, this is a protective measure, but in the case of chronic damage, this process gets out of control, causing the growth of fibrous tissue and a gradual deterioration of liver function.
Can the development of fibrosis in the liver be stopped?
Yes, the development of liver fibrosis can be stopped, and in some cases, even partially reversed.This is possible with early diagnosis and proper treatment aimed at eliminating the cause of liver damage and improving its overall condition. Here are the main approaches to stopping the progression of fibrosis:
1. Treating the underlying cause
Antiviral therapy: In the case of chronic hepatitis B or C, antiviral treatment helps reduce the viral load and inflammation in the liver, which slows down or even stops the progression of fibrosis.
Treating NAFLD: In the case of non-alcoholic fatty liver disease, losing weight, changing your diet, and increasing physical activity are important to reduce fat accumulation and inflammation in the liver.
Abstaining from alcohol: Stopping alcohol completely can significantly slow down or stop the progression of fibrosis in patients with alcoholic liver disease.
Treating autoimmune diseases: Using immunosuppressants or other drugs can help reduce inflammation in autoimmune liver diseases.
2. Using drugs aimed at reducing fibrosis
Antifibrotic drugs: Various drugs are currently being studied to block the pathways that form fibrous tissue. Some of them are already showing promising results in clinical trials.
Antioxidants: Substances such as vitamin E can help reduce inflammation and slow down the rate of fibrous tissue formation.
3. Support the Liver and Improve Overall Health
Eating a Healthy Diet: A diet low in saturated fat and sugar, rich in antioxidants, helps support liver health.
Exercise: Regular exercise helps reduce inflammation and improve metabolism, which can help reduce the fat load on the liver.Weight Control: Losing weight (if needed) helps reduce liver fat and stop fibrosis from progressing.
4. Avoiding Toxins and Harmful Substances
Avoiding Hepatotoxic Drugs and Chemicals: It is important to monitor medications that can damage the liver and minimize exposure to toxic substances.
Healthy Lifestyle: Not smoking and limiting exposure to harmful chemicals can help protect the liver.
5. Medical Monitoring and Control
Regular checkups and monitoring of liver enzymes and other markers help doctors monitor the health of the liver and the effectiveness of treatment. Fibrosis can be diagnosed using non-invasive methods such as elastography and traditional methods such as liver biopsy.
6. Liver Repair and Regeneration with Stem Cells
The liver has the ability to regenerate. If the underlying damage is repaired, liver cells can regenerate and scar tissue can shrink over time. This is especially likely in the early stages of fibrosis. With stem cell therapy, you can completely get rid of liver fibrosis.
How stem cells help with liver damage,
The use of stem cells to restore the liver in cirrhosis is a promising direction in medicine, which is used to replace damaged liver cells and stimulate tissue regeneration. Cirrhosis is a severe stage of liver damage, in which normal organ tissue is replaced by scar tissue, which leads to deterioration of liver function.Stem cells have a number of unique properties that may be useful for liver regeneration:
1. Tissue regeneration potential
Stem cells have the ability to self-renew and differentiate into various cell types, including hepatocytes (liver cells). This allows them to be used to replace damaged liver cells and restore normal tissue.
2. Liver regeneration mechanisms
Stem cells can regenerate the liver in several ways:
Direct differentiation: Injection of stem cells can lead to their transformation into functional liver cells that replace damaged areas.

Paracrine effect: Stem cells secrete biologically active substances (cytokines, growth factors, and anti-inflammatory molecules) that stimulate the processes of repair and regeneration of surrounding tissues. These substances can also reduce inflammation and promote remodeling of scar tissue.
Immunomodulation: Stem cells can influence the immune system, reducing inflammation and slowing the development of fibrosis.
Benefits of using stem cells
Restoring liver function: Stem cells can restore or improve liver function, reducing the need for an organ transplant.
Minimizing side effects: Using the patient’s own stem cells (autologous) reduces the risk of rejection and side effects associated with the immune response.
Using hepatocyte cells in therapeutic therapy, how do they affect the liver?
In stem cell therapy, hepatocytes (the main cells of the liver) are restored through several mechanisms that help regenerate tissue and improve liver function. Here is how stem cells help restore hepatocytes:
1. Direct differentiation of stem cells
Embryonic stem cells can differentiate into hepatocytes. This means that when grown in a laboratory, they turn into cells that are similar in function and structure to normal liver hepatocytes. Such cells can replace lost or damaged hepatocytes and help restore liver tissue.
2. Paracrine effect
One of the most significant restoration mechanisms is the paracrine effect. Stem cells secrete biologically active molecules such as:
Growth factors (e.g. HGF – hepatocyte growth factor),
Cytokines,
Anti-inflammatory molecules.
These substances stimulate existing hepatocytes to regenerate, divide and restore function. Paracrine signals can also attract other cells that are involved in the restoration of damaged tissue and the reduction of inflammation.
3.Immunomodulation
Stem cells can modulate the immune response by reducing inflammation that often accompanies liver injury. This helps create a more favorable environment for tissue repair. Reducing inflammation helps reduce damage to hepatocytes and improve their ability to regenerate.
4. Activating hepatic stellate cells
Hepatic stellate cells (Ito cells) play a role in the accumulation of vitamin A and in fibrosis processes. Stem cells can influence these cells, preventing their activation in a state that leads to the formation of fibrous tissue. This helps reduce the development of scar tissue and preserve the functional capacity of the liver, which gives hepatocytes more opportunities for recovery.
5. Improving the liver microenvironment
The introduction of stem cells helps improve the blood supply and microenvironment of the liver, which helps deliver essential nutrients and oxygen to hepatocytes. Improving microcirculation helps speed up regeneration processes and restore normal liver function.
6. Stimulation of endogenous regeneration
Stem cells can activate the liver’s own regenerative processes. The liver has a unique ability to self-repair, and stem cells can enhance this ability by stimulating the proliferation of the remaining healthy hepatocytes.
What is the success rate of stem cell treatment for cirrhosis?
READ MORE ABOUT RESULTS AND SUCCESS RATES:Stem Cell Therapy Success Rate: What Patients Should Know About Effectiveness and Results
Clinical trials have shown that some patients with cirrhosis experience significant improvement in liver function and even partial restoration of tissue structure.However, the success rate varies and depends on the stage of cirrhosis, the type of stem cells used (e.g. mesenchymal stem cells or induced pluripotent stem cells), and the individual characteristics of the patient.
The success rate of treatment can reach 50-70% in terms of clinically significant improvements, but this does not mean a complete cure. Data on complete liver recovery in advanced stages of cirrhosis are still rare.
Factors affecting success:
1.Stage of cirrhosis: In the early stages, treatment results can be more successful than in advanced cirrhosis.
2. Source and type of stem cells: Mesenchymal stem cells and induced pluripotent stem cells show different results. The combination of cell cultures is also important, taking into account the individual medical history of the patient.
To achieve a lasting recovery, the patient must monitor the level of liver function, periodically take control tests, and, if necessary, do elastography (fibroscan) to assess the quality of liver tissue.
