Are there organelles inside cancer cells? If so, how is it different from primary cells?

Organelles are definitely there because cancer cells are transformed from human cells and belong to eukaryotic cells. The proportion will also vary from that of the primary cell, as the structure determines the function. First of all, it can proliferate indefinitely, which requires a large amount of protein, so there will be more ribosomes; In addition, DNA replication and DNA expression require a large amount of ATP, and in order to meet it, there must be more mitochondria corresponding to it; In addition, there are fewer glycoproteins on the surface of its cell membrane, indicating that the organelles that synthesize the substance are reduced (or the pathway for the synthesis of the substance is blocked, but the organelles are not reduced).

Cancer cells should also have organelles, after all, they are also mature eukaryotic cells.

However, cancer cells should be highly undifferentiated, that is, they should not have any other structure that is unique to cells, but they should also be common to everyone......

That's how I understand it......

1. The morphological structure is different.

Under normal circumstances, the size and morphological mechanism of cells in the same tissue are basically the same, and there is only one nucleus in normal cells, and there is a certain proportion between the nucleus and the cytoplasm. Cancer cells are different in these aspects, first of all, the size and morphological structure of cancer cells are inconsistent, and the volume of nuclei in cancer cells is also diverse, there will be meganucleus, binucleus, multinucleus or heteromorphic nuclear morphology, and the quality and quantity of cytoplasm are also different from normal cells, which is also the fundamental reason for the diversity of tumors in cancer patients.

2. Cell metabolism is different.

Normal cells and cancer cells are living cells, normal cells participate in the body's metabolism every day to maintain cell life, its metabolism includes sugar, protein, enzyme and genetic cytoplasmic nucleic acid metabolism, and cancer cells are very different from normal cells in metabolism, when the synthesis of proteins and nucleic acids is vigorous, the catabolism of cancer cells will be reduced, resulting in metabolic imbalance, when the protein metabolism of cancer cells is vigorous, it will seize the protein decomposition products of normal tissues to synthesize the proteins needed by cancer tissues, It leads to the patient's physical weakness or cachexia, which is one of the reasons why the metabolism of cancer cells is increased and harmful to the human body.

3. Different growth methods.

Not to mention the growth mode of normal cells here, cancer cells have two main characteristics compared with normal cells, the first is the autonomy of cancer cell growth, cancer cells often show uninterrupted reproduction and differentiation after being out of the control of the body, this is autonomy, in the process of disease development, the stronger the autonomy, the faster the disease develops, and the larger the tumor. In addition, the invasion and metastasis of cancer cells, which is the most important feature that distinguishes tumors from benign and malignant, malignant tumors will be invasive and metastatic, normal cells are adhesive to each other, and when the surface of cancer cells changes, the adhesion will be weakened, and cancer cells are prone to fall off, dissolve or invade the blood, lymph, surrounding tissues, and spread to all parts of the body, resulting in metastasis.

Hello, re-cancer is a kind of tumor, specifically refers to malignant tumors from epithelial tissue, and BAI cancer du refers to malignant tumors that seriously endanger human health, such as DAO leukemia, lung cancer, liver cancer, etc. Benign tumors and malignant tumors, and benign tumors are redundant pieces of tissue that grow out of tissues, which generally grow slowly, rarely metastasize, and many can be **.

Cancer cells are quite different from normal cells in terms of morphological structure, metabolic characteristics and growth mode.

Cancer cells are generally larger than their normal counterparts, and cancer cells are also inconsistent in size and morphology with each other. Cells contain both nuclei and cytoplasm, and cancer cells have increased nuclei in size, are inconsistent in morphology, and may have meganucleus, binucleus, multinucleation, or heteromorphic nucleus.

Cancer cells are also living cells with metabolic characteristics that are very different from those of normal tissue cells. It is manifested by the abnormal synthesis of substances such as proteins and nucleic acids that make up the basic structure of cells, while their catabolism is significantly reduced, resulting in an imbalance between synthesis and catabolism.

There are two main characteristics of cancer cell growth.

The first is the autonomy of cancer cell growth, cancer cells are out of the body's control to varying degrees, often manifested as uninterrupted growth, reproduction and poor differentiation. This characteristic is called autonomous or autonomous growth of cancer cells.

The second characteristic of cancer cell growth is infiltration and metastasis, which are the main features that distinguish benign and malignant tumors. Only malignant tumors are invasive and metastasis. A series of changes can occur on the surface of cancer cells, so that the intercellular adhesion is reduced, and cancer cells are easy to fall off, dissolve and invade surrounding tissues or invade blood, lymphoid tissues, and spread to other parts of the body through the circulation of blood and lymphatic fluid, causing the spread and metastasis of cancer.

Cancer cells can pass on their autonomous, infiltrative, and metastatic properties to their offspring cells. The newly multiplied cancer cells have the same characteristics, so the cancer can expand and even spread widely, and the malignant characteristics of the cancer cells will always be maintained.

What are the main characteristics of cancer cells.

The main similarities between stem cells and tumor cells are that they can proliferate in large numbers and differentiate into other cells.

The presence of cancer stem cells is the cause of tumors**.

Killing cells in the G0 phase can greatly improve the ** rate of tumors.

Due to the rapid metabolism of cancer cells, the protein synthesis function is enhanced, and the number of ribose grinding bodies in this cell increases due to the increase of Chongming.

Therefore, c
