The NTCC? HUES8 cell line is a well-known and extensively characterized human embryonic stem cell (hESC) line. It is part of a series of hESC lines (HUES1-9) derived and made available by Harvard University.

Key Characteristics

• Origin: HUES8 cells were derived from the inner cell mass of a human blastocyst at the blastocyst stage of development.

• Pluripotency: As an hESC line, HUES8 is defined by its pluripotency—the ability to self-renew indefinitely in an undifferentiated state and to differentiate into any cell type of the three primary germ layers (ectoderm, mesoderm, and endoderm). This pluripotency has been verified both in vitro and in vivo.

• Genetic Profile: The cell line has a normal karyotype (46, XY), meaning it has the typical number of male chromosomes without major structural abnormalities. It is a stable and reliable model for research.

• Molecular Markers: HUES8 cells express a number of key molecular markers of undifferentiated pluripotent stem cells, including SSEA-3, SSEA-4, TRA-1-60, TRA-1-81, and alkaline phosphatase.

• Doubling Time: Its doubling time is approximately 48 hours.

Research Applications

The HUES8 cell line is a fundamental tool for a wide range of research applications, particularly in the fields of developmental biology, regenerative medicine, and drug discovery. Its primary uses include:

• Studying Human Development: Researchers use HUES8 cells to model the earliest stages of human embryonic development and to understand the mechanisms that control cell fate decisions and differentiation into different cell types.

• Disease Modeling: By differentiating HUES8 cells into specific cell types (e.g., neurons, cardiomyocytes, liver cells), researchers can create in vitro models of human diseases to study their pathogenesis and test potential therapies.

• Drug Screening and Toxicology: The ability to generate large numbers of differentiated, disease-relevant cells from HUES8 makes it a powerful platform for high-throughput screening of new drugs and for assessing the toxicity of various compounds.

• Gene Editing and Functional Genomics: HUES8 has been used as a parent line to create genetically modified versions, such as HUES8 iCas9, which contains a doxycycline-inducible Cas9 system for rapid and efficient gene editing using CRISPR technology. This allows for loss-of-function studies and the investigation of gene function in human pluripotent stem cells.

• Regenerative Medicine: The cell line serves as a source for generating various cell types for potential cell-based therapies, though the ethical and regulatory considerations of using hESC lines are significant.

HUES8 細(xì)胞系

HUES8 細(xì)胞系是一種知名且被廣泛研究的人類胚胎干細(xì)胞（hESC）系。它是哈佛大學(xué)開發(fā)并提供的一系列人類胚胎干細(xì)胞系（HUES1-9）中的一個(gè)。

主要特點(diǎn)

• 來源: HUES8 細(xì)胞源自人類囊胚發(fā)育階段的內(nèi)細(xì)胞團(tuán)。

• 多能性: 作為一種人類胚胎干細(xì)胞系，HUES8 的定義特征是其多能性——它能夠在未分化狀態(tài)下無限期地自我更新，并能分化成所有三種主要胚層（外胚層、中胚層和內(nèi)胚層）的任何細(xì)胞類型。這種多能性已在體外和體內(nèi)得到了驗(yàn)證。

• 遺傳學(xué)特征: 該細(xì)胞系具有正常的核型（46, XY），這意味著它具有典型的男性染色體數(shù)量，且沒有重大的結(jié)構(gòu)異常。它是一個(gè)穩(wěn)定可靠的研究模型。

• 分子標(biāo)記: HUES8 細(xì)胞表達(dá)多種未分化多能干細(xì)胞的關(guān)鍵分子標(biāo)記，包括 SSEA-3、SSEA-4、TRA-1-60、TRA-1-81 和堿性磷酸酶。

• 倍增時(shí)間: 其倍增時(shí)間約為48小時(shí)。

研究應(yīng)用

HUES8 細(xì)胞系是廣泛研究應(yīng)用的基礎(chǔ)工具，特別是在發(fā)育生物學(xué)、再生醫(yī)學(xué)和藥物發(fā)現(xiàn)領(lǐng)域。其主要用途包括：

• 研究人類發(fā)育: 研究人員使用 HUES8 細(xì)胞來模擬人類胚胎發(fā)育的最早期階段，并理解控制細(xì)胞命運(yùn)決定和分化成不同細(xì)胞類型的機(jī)制。

• 疾病建模: 通過將 HUES8 細(xì)胞分化成特定的細(xì)胞類型（例如，神經(jīng)元、心肌細(xì)胞、肝細(xì)胞），研究人員可以創(chuàng)建人類疾病的體外模型，以研究其發(fā)病機(jī)制并測試潛在療法。

• 藥物篩選和毒理學(xué): 利用 HUES8 細(xì)胞產(chǎn)生大量分化的、與疾病相關(guān)的細(xì)胞的能力，使其成為高通量篩選新藥物和評估各種化合物毒性的強(qiáng)大平臺。

• 基因編輯和功能基因組學(xué): HUES8 被用作親本細(xì)胞系來創(chuàng)建基因改造版本，例如 HUES8 iCas9，它包含一個(gè)可由四環(huán)素誘導(dǎo)的 Cas9 系統(tǒng)，可使用 CRISPR 技術(shù)進(jìn)行快速高效的基因編輯。這使得研究人員能夠進(jìn)行功能缺失研究和人類多能干細(xì)胞中基因功能的研究。

• 再生醫(yī)學(xué): 該細(xì)胞系可作為生成各種細(xì)胞類型的來源，用于潛在的細(xì)胞療法，盡管使用人類胚胎干細(xì)胞系涉及重大的倫理和監(jiān)管考量
