Respiratory System Primary Cells

The human respiratory system is composed of a network of tissues and organs that enable the body to absorb oxygen from the air as well as expel carbon dioxide and other waste gasses. These functions are supported by a variety of cells that aid in promoting epithelial homeostasis, preventing alveolar collapse, facilitating the exchange of gasses between the blood and the tissues, and ensuring that the lungs adjust properly to low atmospheric pressure.

Primary cells taken directly from the respiratory tissue of a human subject can simulate in vivo conditions with a very high degree of accuracy and, for that reason, have granted researchers a number of insights into various lung diseases and related medical disorders.

 

Types of Respiratory System Cells

The cells of the respiratory system can be grouped into three distinct categories. These are:

●

Nasal cells – These can be found in the mucosal epithelium of the nasal cavity.

●

Bronchial/Tracheal cells – Taken from the linings of the trachea (the “windpipe,” connected to the larynx) and the bronchi (branched airways connected to the trachea), which all work together to convey air from the atmosphere into the lungs.

●

Pulmonary cells – Cells from human lung tissue can be divided into four subtypes:

○

Epithelial cells– Regulate immune response, clear away particulate matter, and provide barrier protection.

○

Endothelial cells– Manage vascular homeostasis.

○

Smooth muscle cells– Maintain healthy bronchial tone.

○

Fibroblasts– Promote recovery from injury and inflammation.

Uses of Respiratory System Cells

Primary cells from the respiratory system are useful in many research laboratory applications. Bronchial/tracheal cells continue to yield valuable discoveries relating to the causes and progression of respiratory disorders such as asthma, cystic fibrosis, and chronic obstructive pulmonary disease (COPD).

 

Human nasal epithelial cells (HNEpC), which are sensitive to environmental pollutants, are commonly utilized to study the characteristics of viral infections.

 

Human pulmonary cells, a mainstay of many medical research labs, have acquired new relevance in the era of COVID-19. As the SARS-CoV-2 virus causes serious complications most commonly in the lungs, human primary pulmonary cells have become increasingly important in the study of this coronavirus strain.

 

AcceGen offers 41 different types of human respiratory system primary cells that are well suited for research use. Available primary cells include Human Nasal Epithelial Cells (HNEpC), Human Bronchial Epithelial Cells (HBEpC), and Human Type II Alveolar Epithelial Cells (PAEpiC2).

Cancer associated fibroblasts: how do they contribute to cancer progression?

Image
Cancer associated fibroblasts (CAFs), or Carcinoma associated fibroblasts, can contribute to cancer progression through multiple mechanisms, including the secretion of soluble factors and extracellular matrix, physical interactions with cancer cells, the regulation of  angiogenesis , immunity and metabolism, and resistance to chemoprevention according to many present researches. Therefore, CAFs are attracting increasing attention as a therapeutic target in cancer. What is CAF s ? Tumors are multicellular tissues consisting of not only tumor cells but also resident cells in the local stroma. Fibroblasts are a significant portion to the cell composition of most solid tumors, including prostate cancer, lung cancer, breast cancer, gastric cancer, colorectal cancer, and pancreatic cancer. CAF cells, which mainly originate from local tissue fibroblasts, are a heterogeneous population of activated fibroblasts found within the tumor microenviron...

Application of MDA-MB-series Cell Lines in Breast Cancer Research

Image
The Relationship between Breast Cancer and Breast Cancer Cells Breast cancer  is the leading cause of cancer death among women in developed countries[1]. The majority of breast cancer patients are over 50 years old. However, the result of new cases study shows that the number of breast cancer patients under 45 years old has exceeded 10%[2].   Currently, most of the breast cancer knowledge comes from in vivo and in vitro studies using  breast cancer cell lines  because they can provide unlimited amounts of homologous self-replicating material using simple but standard media[3]. Therefore, it is essential to know whether these cell lines can capture molecules well before obtaining any clinically relevant results.   Breast Cancer MDA-MB-series Cell Lines Establishment MDA-MB- series tumor cell lines were established from M. D. Anderson Hospital and Tumor Institute. They have created a total of 19 MDA-MB series of cell lines from female patients ...

Bone Cancer and Bone Cancer Cell Lines

Image
Bone and Bone Cancer Bone The bone is a rigid organ that protects other organs and supports the body[1, 2]. There are about 300 bones in a newborn baby, and some of them will fuse during growth and development, and finally, 206 pieces are left in adulthood[3]. The main structures of bones include the outer cortex composed of dense bone[4], internal cortical bone[5], marrow[6], and cells[5]. Bones have a variety of functions, including a variety of mechanical functions[7], the Synthetic function of bone marrow ( hematopoiesis )[8], and are involved in body metabolism (such as mineral and fat storage,  pH balance regulation , detoxication, and calcium balance regulation). Besides, some diseases or injuries also occur in the bones, such as fractures, tumors, osteoporosis, etc.[9].     Figure.1  Microstructure of bone tissue   Tumor and  B one Cancer Bone has the possibility of tumorigenesis, which may affect the bones to a certain extent. Benign tumors are mos...
