--Mark Hill 07:59, 24 March 2011 (EST) Thank you for your suggested topics for the group assignment. The second question you need to answer was "2. Identify and add a link to your page of a recent cell biology article using confocal microscopy."

2. Identify and add a link to your page of a recent cell biology article using confocal microscopy

MKS and NPHP modules cooperate to establish basal body/transition zone membrane associations and ciliary gate function during ciliogenesis

Topics of Interest for Group Assignment

The mechanisms of cell apoptosis

The cell cycle

Cell signaling

Facilitated diffusion and membrane channels

Cell culture and media


1. Find the SDS information for chloroform and identify the hazards associated with this chemical.

Inhalation: Acts as a relatively potent anesthetic. Irritates respiratory tract and causes central nervous system effects, including headache, drowsiness, dizziness. Exposure to higher concentrations may result in unconsciousness and even death. May cause liver injury and blood disorders. Prolonged exposure may lead to death due to irregular heart beat and kidney and liver disorders.

Ingestion: Causes severe burning in mouth and throat, pain in the chest and vomiting. Large quantities may cause symptoms similar to inhalation.

Skin Contact: Causes skin irritation resulting in redness and pain. Removes natural oils. May be absorbed through skin.

Eye Contact: Vapors causes pain and irritation to eyes. Splashes may cause severe irritation and possible eye damage.

Chronic Exposure: Prolonged or repeated exposure to vapors may cause damage to the nervous system, the heart and the liver and kidneys. Contact with liquid has defatting effect and may cause chronic irritation of skin with cracking and drying, and corresponding dermatitis. Chloroform is a suspected human carcinogen.

Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the substance.

2. You will need to upload an image and add it to your page, with the reference and copyright information with the image. + mice.png

Terminal Schwann cells in transplanted adult muscle are derived from the host.[1]

A. Low magnification view of a wild-type MG muscle transplanted 2 months earlier into a transgenic mouse that expresses EGFP (green) under the direction of the S100 promoter. Endplate ACHRs are stained with α−Btx (red). This panel illustrates the general finding that all endplate staining colocalized with EGFP. B. EGFP fluorescence was absent at motor endplates in an MG muscle from an EGFP-expressing transgenic transplanted into a wild-type host (B1) but the same endplates stained positively for S100 (green, B2), demonstrating that terminal Schwann cells were derived from the host. C. To exclude the possible survival of wild-type TSCs after transplantation of wild-type muscle into the ECFP transgenic (C1), muscle sections were first labeled for S100 (C2) but all labeling was found to colocalize with EGFP fluorescence (C3) providing further evidence that wild-type TSCs did not survive transplantation.

1. Identify a commercial supplier of an antibody that relates to your group project topic.

Anti-acetylcholine receptor antibodies in Myasthenia gravis. Name of antibody: PYK2 [PY881] Supplier: Invitrogen Australia Pty Limited

2. In mitochondria, where is the gene located that encode Cytochrome C and what keeps this protein trapped within the mitochondria?

Cytochrome C is a small heme protein located on the outer surface of the inner mitochondrial membrane. They are trapped inside the mitochondria by the outer membrane of mitochondria. The gene that encode Cytochrome C is located in chromosome 7; MapLocation: 7p15.3


1. Identify from one of the cell line repositories: a neural cell line and a muscle cell line.

Source: Cell line repository - American Type Culture Collection (ATCC)

Neural cell - Cortical Neuron HCN-1A (CRL-10442)

Muscle cell - Muscle Myoblast C2C12 (CRL-1772)

2. Identify the species and growth conditions for these cell lines.

Cortical Neuron - Homo sapiens (human)

Growth conditions:

- Growth media: ATCC-formulated Dulbecco's Modified Eagle's Medium (DMEM). Fetal bovine serum to a final concentration of 10% must be added to DMEM to make the complete growth medium.

- Temperature: 37.0°C

- Growth Conditions: The growth medium must be adjusted to pH 7.35 prior to filtration.

Muscle Myoblast - Mus musculus (mouse)

Growth conditions:

- Growth media: ATCC-formulated Dulbecco's Modified Eagle's Medium (DMEM). Fetal bovine serum to a final concentration of 10% must be added to DMEM to make the complete growth medium.

- Temperature: 37.0°C
