===== Mission Statement =====

One major goal of the 4D Nucleome Network is the integration of a large array of different technologies to study the structure and dynamics of the human genome. The application of these methods to common cells systems using common protocols will greatly facilitate achieving this goal. This working group’s job is to define these protocols for those groups that are working with common systems and for the common systems that will be employed for the 4DN Phase 2 collaborative projects. While individual laboratories will also use lab-specific materials selected for their specific project or technology, wherever possible groups are encouraged to use 4DN Cells WG approved protocols in order for their datasets to be labeled as gold standard for data integration.

**[[https://drive.google.com/file/d/18WTc_jLNfzfekeBaAeKneYTa1r_R7SXi/view?usp=sharing|4DN Cells Legacy Document]] - this document contains a summary of the issues faced and decisions made by the Cells WG in 4DN Phase 1**

===== Objectives =====

1) To answer queries, update protocols, negotiate standard lots of reagents for the 4DN Tier1 and Tier2 cell line in order to define gold standard datasets for data integration. 2) To identify 4DN groups working with common cell systems, and encourage them to work with the Cells WG to establish common protocols that will permit generation of 4DN gold standard datasets for integrative analyses. 3) To establish standard protocols for stocking and maintaining cell samples for the 4DN collaborative projects and establish the metadata requirements for datasets to be designated gold standard datasets for integrative analyses. 5) To establish protocols to engineer and differentiate 4DN approved cell lines and make 4DN members aware of these cell lines to avoid duplication of effort.

**Tier 1 Lines - CLICK ON LINE FOR THE LATEST 4DN GROWTH SOP NECESSARY FOR GOLD STANDARD DATA PRODUCTION!!! NOTE: For cell lines that use FBS, use the negotiated 4DN lot of FBS. **Brief 4DN history of Tier1 lines is provided. The top priorities for Tier1 were that they have a (relatively) stable karyotype and can be expandable to large numbers. Secondary issues that excluded lines from Tier1 were onerous MTAs or licences (e.g. Geron hTERT plasmid construct in RPE), derivation from tumors (e.g. HCT116), lack of consent for public sharing of raw DNA sequence reads and mouse cells. 4DN Cells WG is always willing to consider any changes or any additions to Tiered cells line (Tier1 or Tier2).

Human ESCs offer differentiation toward many different cell lineages. Cells are immortal, and methods for genome engineering are continuously improving. Both fixed and live imaging have been achieved and the motility of the cells has been addressed with cell density and ROCK inhibition. One disadvantage is that they are more challenging to grow and particularly to maintain in an undifferentiated state but in some cases experienced labs could provide fixed material to less experienced labs.</font></font></font>

Disadvantages are that IMR90 is not immortal and may change with passage and will eventually undergo growth senescence, while GM12878 is very difficult to transfect and is a suspension cell line that poses challenges for imaging methods. However, these cell lines will serve a large number of 4DN labs wanting to do big data enabled computational modeling.</font></font></font>

Please use the AICS’s cell culture SOP to culture both the parental and the cell lines in the AICS Cell Collection. The AICS does not recommend thawing the parental WTC-11 cell line using the thawing step outlined in their SOP. Due to slight differences in the banking approach of the parental cell line, they recommend using the thawing step of Coriell’s WTC-11 SOP for optimal post-thaw recovery of the parental WTC-11 cell line. The AICS’s cell culture SOP is periodically updated so always use the link to see the most recent SOP.</font></font></font></font></font>Please carefully read "[[https://drive.google.com/file/d/1RWOTjmSdnJXNYdw3E6vP4iYtdhqFaJMg/view?usp=sharing|supplementary information]]" as well!!!

Since this line was deposited to Coriell by the Gladstone Institute instead of the AICS, WTC-11’s culture SOP found at Coriell is quite different from other engineered WTC-11 deposited by AICS. For 4DN “gold standard” datasets, please use AICS’ cell culture SOP for passaging the cells even if you use the parental “wild-type” WTC-11 (GM25256).</font></font></font></font></font>

===== Standard Operating Protocols for Engineering 4DN Cell Lines =====

These are suggested protocols based on first hand experience from 4DN members

===== Standard Operating Protocols for Cell Stocking and Maintenance =====

**DATASETS GENERATED USING THE APPROVED SOP PRECISELY AND PROVIDING THE REQUISITE METADATA WILL BE MARKED "GOLD STANDARD" - IF YOU DO NOT FOLLOW THESE PROTOCOLS STRICTLY THEN YOUR DATASETS WILL NOT BE DESIGNATED "GOLD STANDARD". MAKE SURE TO CHECK THE CELLS WIKI PAGE EACH TIME YOU START AN EXPERIMENT FOR ANY UPDATES ON REAGENTS, ETC.!!**

Upon submission of data to the DCC, PIs will be asked to authenticate the cellular material from which data were derived, and whether the handling of the cells deviated from the SOPs provided below, which are intended to minimize variability between labs. Authentication criteria for each cell line may differ. THE SOP FOR EACH LINE CAN BE FOUND BY CLICKING ON THE CELL LINE BELOW.
